Radial Bearing 30151954 for TDS11 top drive

The Radial Bearing OEM Ref. 30151954, supplied by Linhai Evergrow as Evergrow Part #60303908, is a replacement component used in the shot pin mechanism of the NOV TDS-11SA top drive. It is identified as Bearing, Radial, Light and forms part of the Shot Pin Assembly OEM Ref. 30151875.

Although the radial bearing is a relatively small component, its condition is important to the mechanical operation of the shot pin assembly. During top drive maintenance, the bearing should be inspected together with the other mating components rather than treated as an independent replacement item.

Role of Radial Bearing 30151954

A radial bearing is designed to support radial loading and allow controlled relative movement between mating mechanical components. Within the TDS-11SA shot pin assembly, the bearing works as part of a group of components designed to maintain the required mechanical relationship between the shot pin mechanism and its surrounding parts.

The shot pin system is subjected to repeated mechanical movement and operating loads during top drive service. As a result, bearing condition can gradually change through normal wear, contamination, inadequate lubrication, or damage to mating components.

A worn bearing may no longer provide the same smooth movement and support as a serviceable component. For this reason, bearing condition should be considered when diagnosing wear or abnormal operation within the shot pin mechanism.

Part of Shot Pin Assembly 30151875

The 30151954 radial bearing is one of the individual components associated with Shot Pin Assembly 30151875, for which Evergrow provides the corresponding replacement assembly under Part #60303750. Related components include:

Shot Pin Assembly: 30151875 / Evergrow 60303750

Shot Pin: 30173958 / Evergrow 60347916

Shot Pin Sleeve: 30151951 / Evergrow 60303902

Housing, Shot Pin: 30151953 / Evergrow 60303906

Bearing Retainer: 30151955 / Evergrow 60303910

These components are associated with the same TDS-11SA shot pin mechanism.

Inspection and Replacement Considerations

During scheduled maintenance or a top drive overhaul, maintenance personnel should check the radial bearing for signs of abnormal wear, rough movement, damage, corrosion, or other conditions that could affect its service performance.

It is also important to inspect the surrounding components. A new bearing installed together with a severely worn sleeve, housing, retainer, or other mating component may not provide the expected result.

When replacing the bearing, correct identification is essential. Customers should verify the OEM Ref. 30151954 and corresponding Evergrow Part #60303908, together with the applicable top drive model, before ordering.
