Deep groove metric ball bearings are especially suitable for high-speed applications due to their minimal contact design which allows exceptional rotating speed.This bearing has rubber seals on both sides to protect the bearing from dust or any possible contamination, which can extend bearing life, and retain the lubricant in the bearing.The chrome steel bearing balls provide durability and resistance to deformity under heavy loads, and the steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. This deep-groove sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Oil and wear-resistant synthetic Steel reinforcement Accepts radial and axial loads Versatile High rotational speed Reduce friction, vibration & noise Fits: Kawasaki KLF220 BAYOU 2WD 1988-2002 KLF300A BAYOU 1986-1987 KLF300B BAYOU 1988-2002 KLF300C BAYOU 1989-2003 KLF400 BAYOU 1993-1999 Yamaha YFB250 TIMBERWOLF 2WD 1992-1998 YFB250FW TIMBERWOLF 4WD 1994-2000 YFM350FW BIG BEAR 4WD 1998 YFM350U BIG BEAR 2WD 1996-1997 YFM400 KODIAK 1993-1999
