Koyo 30308DJR Metric Series Caged Tapered Roller Bearing, 40 mm Dia Bore, 90 mm OD, 1 Row, 25.25 mm W, 80.5 kN Dynamic/90.2 kN Static Load
Tapered roller bearing are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearing, inch series bearing are also available. This type of bearing is suitable for applications that involve heavy or impact loading.
TRAKROL® bearings feature black oxide treated bearing steel. They utilize either a precision ball or tapered roller bearing insert for longer operating life under combination radial and thrust loads. The capacity for combination loads allows the TRAKROL® bearing to be available in plain (cylindrical), V-groove and flanged outside diameter in both stud and yoke styles. Small sizes less than 3 in outside diameter or point diameter use sealed ball bearing inserts. They also use a NYLAPLATE® seal for additional protection. Stud type configurations utilize a metal end plug seal on the roller face providing a long lasting seal. Both bearing types provide a large internal grease reservoir along with special sealing. This makes TRAKROL® bearings an excellent choice where reduced maintenance is required.
