Can handle light to moderate loads, moderate speed, and vibration at high temperatures. All bearings are equipped with close tolerance stainless steel metal shields, an internal silicone contact seal (B-type), and factory lubricated with our HTB550 PFPE base oil, NLGI No. 2, PTFE thickened grease. KX series ball bearings are designed to significantly outlast all other equivalently sized ball bearings in high-temperature service above 180°F up to their rated temperature. This is achieved with superior metallurgy, elastomers and lubrication selected explicitly for service in the specified temperature range.
