Product Features

Feature 1: The round bearing housing assembly is suitable for areas requiring high-precision rotation.
Feature 2: The end is inserted into a G7 precision hole on the mounting plate for positioning installation, providing high repeatability in positioning during maintenance.
Feature 3: The single bearing type bearing housing assembly occupies less space and is suitable for areas with limited space.
Feature 4: The bearing housing assembly has high perpendicularity and coaxiality, making precise positioning during installation easier.

Usage Method

Mounting method of bearing housing set	Detailed explanation of installation
	When mounting standard bearing housing set, counterbored hole or thread hole are used so that they can be mounted from both sides.
	Accurate positioning can be achieved by aligning the machined holes with H7 tolerance on the mounting surface when the guided bearing housing set is installed.

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.

Example of Use

Equipment Name: Sliding Flip Mechanism
Feature 1: A mechanism that uses a pneumatic chuck to flip and transfer the held workpiece.
Feature 2: The bearing housing set is used in a simple cam shape, which can flip over the workpiece while sliding, thereby changing the direction of the workpiece.
