Lubricant Solid Polymer
Product Description Reduce upkeep with bearings that never need lubrication. Inside, an oil-infused solid polymer fills the spaces between the balls to keep them rolling nearly friction- free. The polymer releases the optimal amount of lubricant on startup— never too much or too little. The embedded oil never leaks out, and seals keep dust and contaminants from sneaking in. The sturdy housing bolts down to support shafts as they turn. Powder - Coated Cast Iron Housing — A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust. Set Screw — Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces. Misalignment Capability — Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
