Polymer Press-Fit Spherical Bearings

SDP/SI offers inch and metric maintenance-free self-aligning bearings that are low cost and easy to install.
See Series S99GSB-… and S99GSBM… .

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.

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

Two-Part Plastic Spherical Bearing
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.

Advantages:
Maintenance free
No lubrication
Vibration dampening
Excellent wear resistance
Corrosion resistant
Lightweight
Strong and durable

FOR SHAFT DIAMETERS: 3/16 - 1/2
SELF ALIGNING
EASY TO INSTALL
LOW COST

MATERIAL:
Housing - igumid G
Ball - L280 Polymer

OPERATING TEMPERATURE:
-22°F to +176°F

FEATURES:
Maintenance free
Chemical and UV resistant
Lightweight
Durable

SPECIFICATIONS:
I.D. After Press Fit: .1900 +.0027/+.0008
.2500 to .3750 +.0033/+.0010
.4375 & .5000 +.0040/+.0013

For optimal performance adhere to the specifications for housing bores and recommended shaft sizes. Press fit bearings are meant to be oversized before being press fit. After proper installation into a recommended housing bore, the inner diameter adjusts to meet our specified tolerances.
