RSB205 Rubber Mounted Cartridge Bearing Unit | Anti-Vibration | 25 mm Bore
Compare mounting style, shaft locking, bore range and installation envelope before selecting the alternative.
RCSA200 / RCSB200 Rubber Mounted Cartridge Bearing Units
Buyers evaluating RCSA200 / RCSB200 Rubber Mounted Cartridge Bearing Units should treat it as a rubber mounted cartridge units with cartridge-style outer geometry rather than a bore-only bearing reference. Its construction is rubber-mounted or rubber-cushioned construction, with eccentric or setscrew locking, by model on the shaft.
When reviewing a model, check whether the locking hardware will remain accessible after guards, pulleys or side plates are in place. Maintenance staff need enough room to tighten and release the chosen mechanism without damaging the shaft or dismantling unrelated components. This becomes particularly important on compact machines where the bearing itself is visible but the service approach is restricted.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

Locking-focused buying notes
Buyers evaluating RCSA200 / RCSB200 Rubber Mounted Cartridge Bearing Units should treat it as a rubber mounted cartridge units with cartridge-style outer geometry rather than a bore-only bearing reference. Its construction is rubber-mounted or rubber-cushioned construction, with eccentric or setscrew locking, by model on the shaft.
Applications include fans, blowers, air-handling equipment and compact rotating assemblies. Treat that as context only; dimensions and environment at the real bearing point control the final selection.

Shaft Locking as a Selection Decision
The way an insert secures to the shaft is a functional choice, not a minor suffix. Setscrews, concentric collars, eccentric collars and tapered arrangements each change how the unit is installed, adjusted and later removed.
When reviewing a model, check whether the locking hardware will remain accessible after guards, pulleys or side plates are in place. Maintenance staff need enough room to tighten and release the chosen mechanism without damaging the shaft or dismantling unrelated components. This becomes particularly important on compact machines where the bearing itself is visible but the service approach is restricted.
Do not change locking styles casually during a replacement. Even if the bore and housing dimensions appear correct, the site may already have established procedures and tooling for one type. A different method can alter shaft marking, removal practice and the amount of room required around the inner ring. If a change is intended, record it as an engineering decision rather than letting it happen through an approximate cross-reference.
For repeat orders, keep the locking description beside the product code in the maintenance system. That small detail helps stores separate look-alike units and gives buyers a clear question to resolve when an old label is partly unreadable.
Shaft-locking view
Use the drawing to compare cartridge outside diameter, axial width and seating geometry. Read the printed values rather than scaling the illustration; for modified equipment, send current machine measurements with the enquiry.
Applications
Fans & Blowers
RCSA205 / RCSB205 can be considered for fans & blowers where its rubber-mounted cartridge geometry matches the machine. Outside diameter and cartridge-seat condition determine how the insert is retained in its support.
Air-Handling Equipment
For air-handling equipment, the eccentric (rcsa) / setscrew (rcsb) arrangement changes installation access and shaft retention. Confirm that detail before standardising the spare.
Vibration-Sensitive Machinery
In vibration-sensitive machinery service, use the construction of RCSA205 / RCSB205 only where the actual moisture, contamination and cleaning conditions match the selected product family.
