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:	GB/T 307.1 Grade 0
	Equivalent to JIS B 1514 Class 0

When L is marked with * in the specification table, the outer periphery of the guide section is recessed, and the effective length of D1g6 is only the E dimension section.

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 double 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 double 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 comes standard with an outer ring fixing cover, 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.
