Thin Type T4DB160 Heavy Load Taper Roller Bearing 160x220x32mm

1. Product Overview
T4DB160 is metric standard single row separable tapered roller bearing, standard overall dimension d160×D220×T32mm, belonging to T4DB standard size series tapered roller bearing. It consists of separable inner cone (with rollers and stamped steel cage) and independent outer cup split assembly, inclined tapered roller raceway can simultaneously bear large radial load and one-way axial thrust composite load.
All inner ring, outer ring and tapered rollers adopt fully quenched GCr15 high carbon chromium bearing steel, ultra-precision mirror grinding raceway surface, uniform line contact stress distribution, excellent resistance to alternating heavy impact load under long-time continuous operation of heavy equipment. Separable split design supports separate installation of shaft and bearing housing, greatly simplify disassembly, maintenance and preload adjustment work of heavy transmission system. Widely matched heavy industrial gear reducer, mining equipment transmission shaft, metallurgical auxiliary machinery, large construction machinery walking drive assembly and heavy pump rotating support positions.
