Peer Bearing RCSM-20L Rubber Cast Iron Cartridge Unit Eccentric Collar

Description

Product Overview

The Peer Bearing RCSM-20L is a precision‑engineered cartridge block bearing designed for high‑performance power transmission systems. Its core consists of a conductive rubber interliner that actively dissipates static electricity, paired with a robust cast‑iron cylindrical housing that provides exceptional rigidity and wear resistance. The unit features a 1‑1/4″ bore, a 3‑3/32″ outer diameter, and a 1‑7/8″ inner diameter, making it compatible with a wide range of shaft sizes. The eccentric locking collar simplifies installation while ensuring a secure, vibration‑free fit. A single lip seal protects the internal components from dust, moisture, and other contaminants, extending service life even in harsh industrial environments.

Usage

This cartridge bearing excels in applications where static discharge, noise reduction, and reliable operation are critical. Typical use cases include motor shafts, gearboxes, pumps, and conveyor systems within manufacturing plants, processing facilities, and heavy‑duty equipment. The rubber interliner mitigates electrostatic buildup, which is especially valuable in environments handling flammable or explosive materials. The cast‑iron construction tolerates high radial loads and temperature fluctuations, making the RCSM-20L suitable for continuous operation in factories, automotive assembly lines, and material handling equipment. Its compact dimensions allow integration into tight spaces without sacrificing performance.

FAQ

What size shafts are compatible with the RCSM-20L?

The bearing is designed for a 1‑1/4″ bore, accommodating shafts that match this diameter within standard tolerance limits.

Can the rubber interliner be replaced if it wears out?

Yes, the interliner is a replaceable component. Peer Bearing supplies compatible replacement inserts, and the design allows straightforward removal and installation.

Is the single lip seal sufficient for environments with high moisture?

The lip seal is engineered to resist moisture ingress under typical industrial conditions. For extreme exposure, additional sealing measures can be implemented.

How does the eccentric locking collar differ from a standard locknut?

The eccentric collar provides a self‑aligning, cam‑action lock that secures the bearing with minimal axial movement, reducing installation time and improving repeatability compared to traditional locknuts.

What is the expected service life of the RCSM-20L under continuous operation?

When installed correctly and maintained according to the manufacturer’s guidelines, the bearing can operate for tens of thousands of hours, depending on load and environmental factors.
