RCSA200 / RCSB200 Rubber Mounted Cartridge Bearing Units
Compare mounting style, shaft locking, bore range and installation envelope before selecting the alternative.
RSB205 Rubber Mounted Cartridge Bearing Unit | Anti-Vibration | 25 mm Bore
RSB205 Rubber Mounted Cartridge Bearing Unit | Anti-Vibration | 25 mm Bore is a rubber-mounted cartridge bearing units using rubber-mounted or rubber-cushioned construction; this version uses eccentric or setscrew locking, by model. For fit approval, check cartridge outside diameter, axial width and seating geometry.
Before dismantling the support, capture the as-installed condition. Measure the shaft centre above the mounting face, record the fixing-hole locations, and photograph any spacers or non-standard hardware. If the base has been welded, slotted or repaired, treat those dimensions as the current machine reality. An old equipment manual can still be helpful, but it should not overrule what is physically present on the machine today.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

The surrounding use case is typically fans, blowers, air-handling equipment and compact rotating assemblies, but the final choice still depends on the actual machine position and service conditions.

Legacy Footprint Review
Replacement work on an older machine is rarely as simple as reading the code on the bearing housing. The useful question is whether the new unit will occupy the same physical relationship to the shaft and frame after years of repairs, shimming or local modifications.
Before dismantling the support, capture the as-installed condition. Measure the shaft centre above the mounting face, record the fixing-hole locations, and photograph any spacers or non-standard hardware. If the base has been welded, slotted or repaired, treat those dimensions as the current machine reality. An old equipment manual can still be helpful, but it should not overrule what is physically present on the machine today.
Keep the removed unit until the replacement has been checked. The old part can reveal details that a worn label does not: which side maintenance staff approached, where the locking hardware sat, whether a cover was used, and how much clearance existed around the housing. Those clues are especially valuable when two candidate products share the same bore yet use a different footprint or shaft-retention method.
For purchasing, the best record is a short package containing the complete old code, the measured interface, and one wider photo of the installation. This reduces the chance of ordering a visually similar unit that only fails when the shutdown is already underway. Once a replacement fits successfully, update the spare-parts record with the confirmed dimensions rather than keeping an uncertain legacy description.

As-installed dimensions to check
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
RSB205 can be considered for fans & blowers where its rubber-mounted cylindrical 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 setscrew 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 RSB205 only where the actual moisture, contamination and cleaning conditions match the selected product family.
