Product Information

These two cam follower part numbers are associated with the carriage assembly of the NOV TDS-11SA top drive. When preparing replacement parts, the OEM reference number and Evergrow part number should be checked carefully to ensure the correct component is selected.

What Is a Cam Follower?

A cam follower is a mechanical component designed to work with a cam or guided surface while allowing controlled movement between connected components. In a top drive carriage assembly, cam followers form part of the mechanical arrangement that supports and guides carriage movement.

Because the carriage operates as part of the top drive support system, the condition of its associated components is important during regular inspection and maintenance. Wear, surface damage, looseness, or other abnormal conditions should be checked according to the equipment manufacturer's maintenance procedures.

Why Cam Follower Condition Matters

The carriage assembly is exposed to repeated mechanical movement during top drive operation. Over time, components within the carriage mechanism may experience normal wear or require replacement during scheduled maintenance.

A worn or damaged cam follower may affect the condition of the associated mechanical contact surfaces and can increase maintenance requirements if it is not identified in time. For this reason, maintenance teams should inspect carriage components regularly and replace parts when their condition no longer meets the required service standards.

When replacing a cam follower, it is important to confirm the part number, application, and corresponding carriage configuration rather than selecting a component based only on appearance.
