Introduction

& nbsp; features double row angular contact ball bearing is composed of inner ring, outer ring, ball and solid cage components. The material of the cage includes nylon, stamped steel plate or brass. The structure of double row angular contact ball bearing is similar to a pair of slightly narrowed angular contact ball bearings arranged in the type of o . but the difference lies in the design of contact angle and ferrule. bearings are divided into open and sealed designs. Due to the standardized manufacturing process, the outer ring of the open bearing is machined with a groove for placing a sealing ring or a dust cover. The sealed bearing is maintenance free, so it can realize special economic bearing arrangement. angle adjustment function of angular contact ball bearing is very limited. double row angular contact ball bearing can bear bidirectional axial force and higher radial force. Double row angular contact ball bearings are particularly suitable for bearing configurations that require axial rigid guidance. axial bearing capacity depends on contact angle; that is to say, the larger the contact angle is, ( contact angle & alpha; = 25 & deg;, 35 & deg; and 45 & deg; ) , the larger the axial load the bearing can bear. 38.. - B , 30.. - B , 32.. - B and 33.. - B series bearings are inseparable and there is no ball loading gap on the end face of the ferrule. Contact angle & alpha; = 25 & deg;. The bearing capacity of double row angular contact ball bearing is the same in two directions. These bearings are widely used. 32 and 33 series angular contact ball bearings are not separable and have a ball loading gap on one side. Contact angle & alpha; = 35 & deg;. these series of bearings should be installed without raceway on the side of the ball gap to bear the main load. 33.. - Da series bearings are double inner ring structures. Contact angle & alpha; = 45 & deg;, so it can bear large axial load in two directions. double inner rings are matched for specific bearings, and even the double inner rings of the same size bearings cannot be replaced with each other. 38.. - B , 30.. - B , 32.. - B and 33.. - B series bearings are 2rsr indicating that both sides are sealed with lip seals. Contact seal is used to prevent the invasion of dust, pollutants and moisture. suffix 2Z indicates that both sides of the bearing adopt clearance seal. sealed bearings are lubricated with high-quality grease, which can meet the lubrication requirements in the bearing operation life cycle. the operating temperature range of open design bearing is & ndash; 30 ℃ to + 150 ℃. limited by cage material, the working temperature of the bearing with glass fiber reinforced nylon cage can reach + 120 ℃. limited by lubricants and sealing materials, the bearing working temperature with suffix 2rsr can reach + 110 ℃. bearings without cage suffix are standard cages made of stamped steel plates. the suffix of angle contact ball bearing with glass fiber reinforced nylon solid cage is TVH . suffix m indicates that the bearing has a brass solid cage with ball guide.
