NKX25Z NAX2530Z Combined Bearings 25 * 37 * 42 * 30mm Needle Roller Thrust Ball Bearing with Cage NKX25 Z

BearingsBearingNeedle roller / thrust ball bearings,NKX seriesNeedle roller / thrust ball bearings in the NKX series combine a radial needle roller bearing and a thrust ball bearing based on the 511 series. They are able to support single-direction axial loads in addition to radial loads. They also permit relatively high-speed operation.NKX .. Z series needle roller / thrust ball bearings are non-separable. They have a stamped steel cover that extends over the shaft washer of the thrust ball bearing. It is firmly attached to the housing washer that is integral to the needle roller bearing outer ring. The cover makes these bearings non-separable. Supplies the thrust ball bearing in this series filled, as standard, with a high-quality grease that has good rust inhibiting properties.The cover, which has no lubrication holes, forms a gap-type seal with the shaft washer to retain the grease in the bearing.Features:Needle bearings are roller bearings with cylindrical rollers. The advantages of needle roller bearings are small radial cross-sectional dimensions and high radial loads. Suitable for use in restricted installation spaces.Steel cage guides and evenly spaced rollers reduce friction, vibration and noise. Heat resistant and durable under heavy loads.
