SpinCo 1-1/4″ Insert Bearing with Cam Lock Collar – CSA207-20

Description

Product Overview

The SpinCo 1-1/4″ insert bearing is a precision‑engineered component designed for demanding power transmission applications. Constructed from high‑grade steel, the bearing features a narrow 72 mm inner race that fits tightly onto shafts while the outer cylindrical race provides a stable, durable interface with housings. The cam (eccentric) lock collar enables a quick, secure attachment that resists loosening under vibration and torque, making it ideal for machinery that experiences frequent start‑stop cycles.

Every bearing is pre‑lubricated with a high‑performance grease that reduces friction from the moment of installation, extending service intervals and minimizing downtime. The lubrication system is sealed to protect against contaminants, ensuring consistent performance even in harsh industrial environments. The design complies with ISO standards for insert bearings, guaranteeing dimensional accuracy and interchangeability with a wide range of equipment.

SpinCo’s commitment to quality is reflected in the rigorous testing each bearing undergoes. Tests include dynamic load simulations, temperature cycling, and corrosion resistance assessments. This thorough validation process ensures that the bearing can handle radial and axial loads typical of conveyors, gearboxes, and motor assemblies without premature wear.

In addition to its mechanical robustness, the bearing’s compact form factor allows for easy integration into space‑constrained designs. The 1-1/4″ size provides a balance between load capacity and footprint, making it suitable for both new equipment builds and retrofits of existing machinery. The cam lock collar’s ergonomic design simplifies installation, requiring only a simple turn to lock the bearing in place.

SpinCo offers this insert bearing under the model numbers CSA207-20, FHR207-20, RA104RR, and AELS207-104N, providing flexibility for customers who need specific part numbers for inventory or compatibility reasons. Each variant maintains the same core specifications, ensuring that performance expectations are met regardless of the exact catalog reference.

Overall, the SpinCo 1-1/4″ insert bearing delivers a combination of durability, ease of installation, and reliable operation that meets the rigorous demands of modern industrial applications.

Usage

This bearing is ideally suited for a variety of industrial settings, including material handling equipment, high‑speed conveyors, and precision machining tools. Its cam lock mechanism allows maintenance personnel to replace or service the bearing quickly, reducing machine downtime and labor costs. The pre‑lubricated design means that the bearing can be installed and put into service immediately, without the need for additional greasing steps.

In environments where temperature fluctuations are common, such as metalworking shops or food processing plants, the bearing’s sealed lubrication protects against moisture and dust ingress. This protection helps maintain consistent performance even when operating under fluctuating thermal conditions, ensuring that the bearing’s load‑carrying capacity remains stable.

Engineers often select this insert bearing for applications that require precise alignment and repeatable positioning. The cam lock collar provides a deterministic locking position, which is essential for equipment that must maintain exact shaft alignment to avoid vibration and wear on adjacent components.

FAQ

What size shaft does this bearing fit?

The bearing is designed for a 1-1/4″ (31.75 mm) shaft diameter, with a narrow inner race that provides a tight fit for precise alignment.

Is the bearing suitable for high‑speed applications?

Yes, the bearing’s robust outer race and sealed lubrication allow it to operate reliably at high rotational speeds common in conveyor and motor applications.

Can the bearing be re‑lubricated after installation?

While the bearing comes pre‑lubricated, it can be re‑greased if needed. The sealed design helps retain lubrication, but periodic maintenance can extend its service life.

What is the load capacity of this insert bearing?

The bearing is rated for typical radial loads encountered in industrial machinery; exact load ratings are provided in the technical data sheet and depend on operating conditions.

How does the cam lock collar work?

The cam (eccentric) lock collar rotates to lock the bearing onto the shaft, creating a secure, vibration‑resistant connection that can be released with a simple turn for maintenance.
