Plastic Spherical Bearings

Precision Spherical Bearings


The spherical ball is made of wear-resistant L280 polymer and the housing is made of shock-resistant reinforced plastic. These bearings can operate at speeds up to 100 ft/min (30.48 m/min) due to the low friction coefficient. 80% lighter than steel, they have a high strength-to-weight ratio and long service life. The pivoting capability offers many design advantages and simplified assembly.


Specifications

SDP/SI offers inch and metric maintenance-free self-aligning bearings that are low cost and easy to install.

Injection molded from high-performance plastics, these bearings are used in various
applications where lubricated metal bearings are not suitable. They are lightweight,
vibration dampening and provide excellent performance in water, chemicals, and dusty
environments.

Operating temperature range:
-22°F to +176°F (-30°C to +80°C)

Applications:
Where ease of assembly is required
Small installation space
Harsh environments

Technical Information for Spherical Bearings
Installation:
For successful operation it is important that bearings are installed properly. The bearings are oversized before press fitting and will not meet listed specifications. Only after press fitting should measurement testing be done.

Bearings should be press fit into the recommended steel housing bore. Bearing should NEVER be hammered into place. Since pivoting allows for misalignment exact orientation of the bearing housing is not critical. Once installed into the housing bore, the inner diameter adjusts to meet the tolerances specified. For optimal performance it is important to follow the recommended specifications for the housing bore (H7) and shaft sizes (h7).
