Couplers & Bearing RCSM-16S Bearing Cartridge

When you are dealing with high-cycle fan assemblies or blower units, the RCSM-16S PEER 1 inch ball bearing cartridge is a standard-setting replacement for handling vibration and static issues. This cylindrical cartridge features a conductive rubber interliner specifically designed to dissipate static electricity and dampen operational noise in HVAC blower applications. Built for a 1" shaft, the RCSM-16S utilizes a narrow inner ring bearing (typically the FHSR205-16) and is secured with reliable set screw locking to ensure the shaft remains locked during startup and high-speed operation. The unit is equipped with RST tight-riding seals and metal shrouds to prevent grease migration and block contaminants in heavy-duty environments. Whether you are performing a field repair on a commercial air handler or an industrial exhaust fan, this rubber-mounted bearing provides the 2.5313" OD required for a precise fit in existing housings.

• Vibration Isolation: The conductive rubber cartridge reduces harmonic transfer in light-to-medium duty blower systems.
• Static Dissipation: Integrated grounding properties prevent charge buildup, protecting sensitive downstream components.
• Precise Shaft Locking: Features dual set screw locking for a secure mechanical bond on 1" cold-rolled or ground shafts.
• Severe Service Seals: RST full-cover metal shroud seals significantly extend service life by retaining factory pre-lube.
• Standardized Fit: 1.0000" bore and 2.5313" OD ensure drop-in compatibility with most OEM industrial air-moving equipment.

Is the RCSM-16S compatible with eccentric collar shafts?
No, the RCSM-16S is a set screw locking model. If your current setup requires an eccentric collar, you likely need the standard RCSM-16. Always verify the locking mechanism on the existing inner ring before ordering.

Can this bearing be used in high-temperature exhaust fans?
While the internal ball bearing can handle standard operational heat, the rubber cartridge is rated for normal HVAC temperatures. For extreme heat applications, verify that the rubber compound meets the specific ambient requirements of the cabinet.

What is the replacement insert for this unit?
This cartridge typically houses the FHSR205-16 bearing insert. If the rubber is still in good condition, you may only need to swap the inner bearing cartridge, though replacing the entire assembly is recommended for optimal noise reduction.
