Igus TSI-0506-04 Sleeve Bearing 5/16 in Id Thermoplastic

Product Description

The IGUS TSI-0506-04 is a plain bore sleeve bearing machined from igus T500 thermoplastic for dry, self-lubricating operation. With a 5/16 inch inside diameter, 3/8 inch outside diameter, and 1/4 inch overall length, this compact bearing supports rotating or sliding shafts without requiring grease or oil. The T500 material is rated for continuous operation from -149 degrees F to 485 degrees F and carries a maximum pressure-velocity rating of 100,000 psi, making it suitable for demanding light-to-medium load applications. It is RoHS II compliant and ships individually. Maintenance technicians, mechanical assemblers, and OEM builders are the typical end users.

The TSI-0506-04 fits standard housings with a bore between 0.3747 and 0.3753 inches and accepts a 5/16 inch shaft. It is well suited for use in HVAC actuators, conveyor guides, small motors, automation equipment, and other mechanical assemblies where periodic lubrication is impractical or undesirable. The plain bore design installs into a round housing without special tooling, making it a straightforward drop-in component for both new builds and field replacements.

Key Features

• Self-lubricating T500 thermoplastic construction eliminates the need for grease or oil maintenance
• Wide temperature range: -149 degrees F to 485 degrees F
• Maximum pressure-velocity rating of 100,000 psi for light-to-medium load service
• Plain bore design for straightforward press-fit installation into a round housing
• RoHS II compliant material
• Compact form factor: 5/16 inch ID, 3/8 inch OD, 1/4 inch overall length

Compatibility

Designed for use in standard round housings with a bore diameter between 0.3747 and 0.3753 inches, accepting a 5/16 inch nominal shaft. Suitable as an OEM-style replacement or new-build sleeve bearing in mechanical and electromechanical assemblies requiring a self-lubricating plain bearing.

Installation Notes

Installation is typically performed by mechanical technicians or assemblers using a press or arbor tool to seat the bearing flush within the housing bore. Verify the housing bore falls within the 0.3747 to 0.3753 inch tolerance range before installation to ensure proper retention. Do not exceed the rated temperature or pressure-velocity limits of the bearing in service. No lubrication is required or recommended for T500 thermoplastic bearings during installation or operation.
