Product Description

Product Overview

It supports and fixes the bearing of the load carrying shaft. The bearing can be accurately and conveniently assembled onto the mechanism using the holder.

Dimensional Drawing

Bearing Precision:	(Radial Bearing) GB/T 307.1 Grade 4, equivalent to JIS B1514 Grade 4
	(Deep Groove Ball Bearing) GB/T 307.1 Class 0, equivalent to JIS B 1514 Class 0

When delivered, the radial bearing unit is not assembled into the housing body

Please secure the outer ring of the radial bearing unit with a dedicated cover plate, and fasten the inner ring with a bearing locknut or similar before use

There is an approximately 1 mm gap on both the left and right sides of the housing on the deep groove ball bearing side, so the inner ring can be fixed without adjusting the length of the inner ring spacer

The deep groove ball bearing side (5) comes with a standard cover plate

For the radial side (6), you can choose one from the N standard cover plate, S oil seal cover plate, or R O-ring cover plate

The oil seal cover plate and O-ring cover plate do not include the shaft collar (7)

Contact with the O-ring may apply torque

Product Features

Feature 1: The round bearing housing assembly is suitable for locations requiring high-precision rotation.
Feature 2: Compared with the single bearing type, the triple bearing type bearing housing set is more suitable for heavy load operating environments, and keeps transmission products such as rotating shafts fixed.
Feature 3: The three-bearing type bearing housing assembly is very convenient for cantilever support.
Feature 4: The bearing housing assembly has high perpendicularity and coaxiality, making precise positioning during installation easier.
Feature 5: The outer ring fixed type of the radial bearing housing assembly is equipped with an outer ring fixing cover as standard, which prevents the bearing outer ring from moving in the thrust direction.

Precautions

Precautions	Illustration and Reference
Anti-rust performance and maintenance of metal materials and surface treatment.	For detailed rust prevention performance and maintenance, please refer to the technical documentation.
Bearing accuracy for bearing housing assembly: GB/T 307.1 Class 0 (equivalent to JIS B 1514 Class 0) When selecting mating parts, please choose products with negative tolerance.	For detailed bearing specifications, please refer to the technical documentation.
When selecting, please note that axial clearance exists between the bearing and the retaining ring. Axial direction: The direction along the rotational central axis of cylinder, which is the same direction as the central axis. (Blue direction shown on the right) Radial direction: perpendicular to the axial direction, which is the radius or diameter direction of the end face circle of the cylinder. (Red direction shown on the right)
The retaining ring in the bearing housing set with retaining ring cannot be fastened axially, and it only plays a role in preventing the bearing from falling off. If you need to tighten the bearing axially, it is recommended to use a retaining ring, nut, etc. When choosing a fixing ring, nut, etc. for axial tightening, please take care to avoid the retaining ring. Please refer to the product specifications for retaining ring dimensions.
