Koyo RCB-162117-FS Roller Clutch and Bearing, DC Type, Open, Nylon Cage, Inch, 1″ ID, 1-5/16″ OD, 1-1/16″ Width

Description

Product Overview

The Koyo RCB-162117-FS roller clutch and bearing is engineered to deliver precise one‑directional torque transmission while allowing free overrun in the opposite direction. Constructed with a drawn steel outer shell, the cup features a minimal cross‑section that enables installation in confined mechanical assemblies where space is at a premium. The clutch incorporates a polyamide nylon cage that houses stainless steel pressure springs on each roller, ensuring consistent engagement and disengagement under varying load conditions.

Each roller is fabricated from through‑hardened, high‑carbon chromium steel, providing exceptional heat tolerance and durability when subjected to heavy radial loads. The dual roller bearing arrangement at both ends of the clutch further enhances load‑carrying capacity, distributing stresses evenly across the assembly. With dimensions of 1″ ID, 1‑5/16″ OD, and a width of 1‑1/16″, this unit fits standard shaft sizes commonly found in industrial power transmission applications.

Despite being discontinued by the manufacturer, the RCB‑162117‑FS remains a sought‑after component for legacy equipment refurbishment, offering a reliable solution for maintaining original performance specifications. Its robust construction, combined with Koyo Torrington’s reputation for precision engineering, makes it a dependable choice for engineers seeking to replace worn or damaged clutches without compromising system integrity.

Usage

This roller clutch and bearing assembly excels in environments where controlled torque direction is critical, such as conveyor drives, gearboxes, and industrial machinery that require a fail‑safe overrun capability. The open‑type design allows for easy integration into existing shafts, making it suitable for retrofitting projects and upgrades in manufacturing plants, material handling systems, and processing equipment.

Because of its compact footprint, the RCB‑162117‑FS can be employed in tight spaces like robotic arms, compact motor housings, and portable equipment where traditional clutch designs would be too bulky. Its high‑temperature tolerance ensures reliable operation in applications that generate significant heat, such as high‑speed drives and heavy‑duty compressors.

Maintenance personnel appreciate the straightforward installation process: the nylon cage can be pressed onto the shaft without the need for specialized tools, and the roller bearings provide smooth rotation with minimal friction, reducing wear and extending service intervals.

FAQ

What size shaft does the RCB‑162117‑FS fit?

The clutch is designed for a 1‑inch inner diameter shaft, with an outer diameter of 1‑5/16 inches and a width of 1‑1/16 inches, making it compatible with standard industrial shafts.

Can this clutch be used in high‑temperature environments?

Yes, the high‑carbon chromium steel rollers are through‑hardened to tolerate elevated temperatures, allowing reliable operation in applications that generate significant heat.

Is the nylon cage prone to wear over time?

The polyamide nylon cage is engineered for durability and resistance to wear. When used within the specified load limits and proper lubrication guidelines, it maintains its performance for the expected service life.

How does the one‑way torque feature benefit my equipment?

The one‑way torque transmission allows the clutch to transmit power in the intended direction while permitting free overrun in the opposite direction, protecting downstream components from reverse torque damage.

What support is available if I encounter installation issues?

Our technical support team provides step‑by‑step installation guidance, including recommended tools, torque specifications, and alignment procedures to ensure a successful fit.
