CSK 35 CZH 35x72x17 One Way Bearing Clutch

Main description

CSK 35 CZH 35x72x17 is a one way bearing clutch designed to transmit torque in one direction while allowing free rotation in the opposite direction in industrial drive systems.

In the category of one way bearings and overrunning clutches, the CSK series is one of the most widely used solutions for compact installations where reliability and precise torque transfer are required. This model combines the functionality of a clutch bearing and a backstop bearing, making it highly versatile across multiple industries.

Unlike standard rolling bearings, this one way bearing operates as a mechanical locking system. When rotation occurs in the driving direction, internal elements engage and transmit torque. When rotation reverses, the mechanism disengages, allowing smooth free movement without resistance. This makes CSK 35 an ideal solution for systems that require directional control.

Construction and design

The CSK 35 one way bearing is based on a compact design integrating clutch functionality inside a standard bearing envelope. The internal mechanism typically uses precision rollers or sprag elements that engage instantly under load.

This design allows the bearing to be installed similarly to deep groove ball bearings, without requiring additional space or complex mounting procedures. The outer ring and inner ring are hardened for durability, while the internal locking mechanism ensures consistent performance under dynamic loads.

The compact geometry of 35x72x17 makes it suitable for applications where space optimization is critical.

Application in industrial systems

CSK 35 clutch bearing is widely used in industrial environments where controlled motion and safety are essential. It plays a key role in preventing reverse rotation and protecting machinery.

Typical applications include:

conveyor systems as backstop bearing
gearboxes and transmission systems
electric motor drives
packaging and processing machines
automation lines and transport systems
agricultural and mining machinery

In conveyor systems, it prevents rollback of transported material. In drive systems, it ensures directional torque control.

Operational advantages

Using a one way bearing clutch like CSK 35 provides several operational benefits:

prevents reverse rotation and system damage
reduces need for complex braking systems
ensures smooth and automatic engagement
compact and easy to install
high reliability in continuous operation
compatible with standard industrial setups

The design minimizes maintenance while improving system safety and efficiency.

FAQ

What is the difference between a one way bearing and a standard bearing
A one way bearing transmits torque in only one direction, while a standard bearing allows rotation in both directions.

Can CSK 35 be used as a backstop bearing
Yes, it is commonly used as a backstop bearing in conveyor and transport systems.

Does this bearing require additional lubrication
It depends on application conditions, but standard lubrication is usually sufficient for most industrial uses.

Is CSK 35 suitable for high speed applications
It can operate at moderate to high speeds, but performance depends on load and lubrication conditions.

Can it replace a clutch mechanism
Yes, in many applications it replaces traditional mechanical clutches with a more compact solution.
