Bearings-Axial Angular Contact Ball Bearings ZKLN1747-2RS
Axial angular contact ball bearings ZKLN..-2RS correspond toseries ZKLN but have a runout tolerance within P5, less stringent diameter tolerances . They are used where a lower positional accuracy is acceptable. As a result, the adjacent construction does not need to be as accurate with these bearings. Bearings with the suffix 2RS have lip seals and highly effective sealing The bearings are greased using a lithium soap grease to GA28 and can be lubricated via a lubrication slot and lubrication holes in the outer ring. For the majority of applications, the initial greasing is sufficient for the whole bearing operating life. Operation tempreture: Sealed axial angular contact ball bearings are suitable for operating temperatures from 30 °C to +120 °C, restricted by the grease, the seal material and the plastic cages in the ball and cage assemblies. The operating temperature influences the dynamic bearing characteristics. The values given in the dimension table are based on a room temperature of +20 °C. Application: Auto, tractor ,machine tool, electric machine, water pump, agricultural machinery and textile machinery.
