JKL MAKE 4.063 RECTANGULAR COMBINED BEARING


Linear Bearing for Axial & Radial LoadsPrior to welding, disassemble bearing components. To avoidcracks in welded joints, please use welding electrodes and coreweld for unalloyed steel.
MATERIALSOuter ring – Case-hardened steel En 31 - SAE 52100 hardenedat 60+2 HRc


Inner ring – Hardened steel En 31 - SAE 52100 hardened at62-2 HRc
Cylindrical rollers – Flat ground heads are hardened steel,En 31 - SAE 52100, hardened at 59-64 HRC
Bolt tolerance = 0.05 mm
Profile rails – High Quality 18MnNb6 Steel at standard lengthsof 6m (19.7 ft). Yield point of 430 n/mm2, Tensile Strengthof 550-770 N/mm2. Rails are not hardened but have a Brinellhardness of 160-210. The guide ways in the rails should belightly greased and not painted.
Clamp flange – Low carbon steel, adjustable clamp
Flange plate – Low carbon steel. Special designs available,contact manufacturer.
Seals – Bearings with fixed axial bearing (JKL-053 to JKL-063) - radial bearing has steel labyrinth and side guide rollerwith rubber seals.
Bearings with eccentric adjustable axial bearing (JKL-454to JKL-463) - Both radial and axial bearings utilize rubber
