1098002650 6WG1 Diesel Engine Parts Ball Bearing

Part number 1098002650 is the original ball bearing provided by ISUZU (Isuzu) for the 6WG1 series large displacement diesel engine. This component is typically used for accessory drive systems of engines, such as supporting bearing seats for generators, air conditioning compressors, fans, or water pumps. Its universal models cover all Hitachi ultra large mining equipment equipped with 6WG1 engines, mainly including EX3600-5/6, EX2600-5, ZX850-5, ZX870-5G and other ultra large hydraulic excavators and mining dump trucks of 80 tons or more. As a precision rolling bearing designated by the original factory, its inner and outer diameters, width, and mounting holes are precisely matched

This product is a deep groove ball bearing, with both the inner and outer rings made of high carbon chromium bearing steel. After precision grinding, it presents a silver gray metallic luster. The raceway and ball bearings have undergone quenching treatment, resulting in high hardness and wear resistance. Internally equipped with a nylon cage to evenly distribute the ball bearings. The outer ring side is engraved with the words "JAPAN" and specification codes such as "55" and "16", indicating that it is made in Japan and has reliable quality. Its typical technical parameters include: inner diameter, outer diameter, and thickness customized according to specific installation positions. The accuracy level is usually P6 or higher, which can withstand high-speed rotation (speed ≤ 6000 rpm) and certain radial loads. The working temperature range is -30 ℃ to+150 ℃, which can adapt to the high temperature environment in the engine compartment.

Installation specifications: 1 Cleaning: Before installation, thoroughly clean the bearing seat holes, shaft necks, and new bearings with a lint free cloth and cleaning agent. 2. Heating installation: For bearings with interference fit, it is recommended to heat them in an oil bath to 80-100 ℃ and quickly and smoothly fit them onto the shaft. Knocking is strictly prohibited. 3. Lubrication: Before installation, fill the bearing raceway with the specified type of high-temperature grease (filling amount is about 1/3-1/2 of the space). 4. Tightening: After installation, ensure that the bearing has no axial clearance but rotates flexibly.
