Corbin Russwin 522F93-2 – Frequently Asked Questions

1) What is the Corbin Russwin 522F93-2 adapter bushing used for?
The 522F93-2 is an adapter bushing for MR (Master Ring) cylinder configurations from Corbin Russwin. It sits inside the cylinder assembly as the interface that lets the master ring seat and align correctly, so it is a service part used when rebuilding or repairing a Corbin Russwin cylinder rather than a complete cylinder you can key and install on its own.
2) Is the 522F93-2 a complete cylinder or just a part?
Just a part. It is catalogued by Corbin Russwin as a replacement component within their cylinder program, model 522F93-2, so it ships as the bushing alone. No plug, no pins, no keys. If you need a working keyed cylinder you are buying a different item.
3) Will the 522F93-2 bushing work in a standard non-master-ring Corbin Russwin cylinder?
No. This bushing is built specifically for MR master ring cylinder configurations. A conventional Corbin Russwin cylinder without a master ring does not use it, and forcing a substitute component into a cylinder rebuild is how you end up with a plug that binds. Confirm the cylinder you are servicing is an MR type before ordering.
4) Is the Corbin Russwin 522F93-2 a cylinder I can key and install, or just a component?
The 522F93-2 is an adapter bushing for MR (Master Ring) cylinder configurations - a replacement part within a cylinder assembly, not a keyed cylinder you install in a door. If you need a complete keyed cylinder instead, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
5) Instead of rebuilding a Corbin Russwin master ring cylinder with the 522F93-2 bushing, what interchangeable-core option could I standardize on?
The 522F93-2 supports servicing an existing Corbin Russwin MR master ring cylinder assembly. If you would rather move the facility to an interchangeable core system, the BEST 1CB is a 150 Series interchangeable core cylinder and the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass 150 Series core. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those paths replace the cylinder rather than rebuild it, so existing MR keying does not carry over.
6) Why would I use a master ring cylinder instead of just switching to interchangeable cores?
A master ring cylinder keeps masterkeying inside a conventional fixed cylinder, so you service it with parts like the 522F93-2 bushing rather than pulling and swapping a core. Facilities that want key control with fast rekeying at the door usually go the interchangeable core route instead, such as the BEST 1C Series standard 5-pin core or the BEST Peaks 1CB 150 Series interchangeable core, or a Schlage 20-057 full size interchangeable core rim cylinder. Those are a system change, not a drop-in for an MR cylinder, so expect to replace housings as well.
7) My Corbin Russwin cylinder is worn out. Should I rebuild it with parts or replace the whole cylinder?
If the housing and plug are sound and only the internal fit is off, an OEM part such as the 522F93-2 MR adapter bushing keeps the existing cylinder and its keying in service. If the cylinder body itself is damaged, replace the cylinder. For replacement cylinders on other hardware, options include the Schlage 20-021 rim cylinder with vertical tailpiece cam or the 20-022 with horizontal cam, and the Detex MC65 mortise cylinder in Schlage C keyway. Those are different keyways and will not carry your existing Corbin Russwin key.
8) Will a BEST 1C5 core or a Kaba Ilco replacement cylinder work in place of the Corbin Russwin 522F93-2?
No. The 522F93-2 is an adapter bushing that seats inside a Corbin Russwin MR master ring cylinder assembly, so it has no key function of its own. The BEST 1C5 is a standard 5-pin cylinder core, and the Kaba Ilco 1539 is a key-in-knob / lever universal cylinder - both are keyed cylinders or cores, not internal bushings, and neither substitutes for the bushing in an MR rebuild.
9) I need a cylinder for a deadbolt or handleset, not a Corbin Russwin MR bushing - what fits those?
The 522F93-2 is a commercial cylinder replacement part for Corbin Russwin MR master ring assemblies, so it does not serve a deadbolt or handleset on its own. For those openings, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder; Medeco's 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
10) For an aluminum storefront deadlock rather than a Corbin Russwin MR cylinder rebuild, what should I order?
The 522F93-2 is an internal adapter bushing for Corbin Russwin MR cylinder assemblies and is not a storefront trim item. For Adams Rite storefront hardware, the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for use with the MS1847 deadlock/deadlatch, the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch, and the 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness.
11) Does the Corbin Russwin 522F93-2 fit Sargent or Falcon cylinders?
No. The 522F93-2 is built to Corbin Russwin specifications as an adapter bushing for its MR master ring configurations, so it is brand-specific. For other lines, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key in lever cylinder in the RU/T Series 6-pin G keyway, keyed different with 2 cut keys.
12) Is this Corbin Russwin part suitable for commercial buildings or is it a residential item?
Commercial. The 522F93-2 is part of Corbin Russwin's commercial cylinder line, and the typical work it shows up in is office, school, healthcare, government, warehouse, multi-tenant residential and retail lock servicing. Locksmiths maintaining a master keyed system across a facility are the usual buyer.
13) How do I make sure I order the right Corbin Russwin cylinder part number?
Order by the manufacturer model, 522F93-2, and confirm it against the MR master ring cylinder you are servicing. Corbin Russwin cylinder service parts are close in appearance and are distinguished by number, not by look, so the number on the order is what gets you the correct bushing.
14) If I only need to fill a cylinder hole with no keying, is the 522F93-2 the right part?
No. The 522F93-2 is an adapter bushing that works inside a Corbin Russwin MR master ring cylinder assembly. For a non-keyed filler in a rim prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the item built for that purpose.
15) Is the Corbin Russwin 522F93-2 suitable for residential hardware like Emtek handlesets?
The 522F93-2 is a commercial-grade Corbin Russwin cylinder replacement part for MR master ring assemblies. For Emtek hardware, the Emtek CY4 cylinder is sold each, the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
16) What is the difference between the Schlage 20-021 and 20-022 if I am replacing a rim cylinder instead of rebuilding a Corbin Russwin MR?
Both Schlage rim cylinders are 6-pin and ship with 2 keys; the 20-021 has a vertical tailpiece cam and the 20-022 has a horizontal tailpiece cam, so the choice follows the cam orientation your exit device requires. The Corbin Russwin 522F93-2 is a different class of part - an adapter bushing used inside an MR master ring cylinder assembly rather than a drop-in rim cylinder.
