Engine Parts
Overview
An engine utilizes a large number of bearings and engine-related parts. The requirements for comfort and convenience in the vehicle have diversified in the car market in recent years, resulting in roomier car interiors with reduced engine sizes. NMT offers compact and durable engine parts that lead the trend toward smaller engines.
Product List
Low friction has been achieved by changing a part of the rocker arm tappet that makes contact with the cam for rolling.
High reliability has been achieved by special grease and high performance seals. NSK offers a wide line of bearings to meet all requirements.
High reliability has been achieved by special grease and high performance seal. NSK offers a wide line of bearings to meet the needs of every type of belt and layout.
Reduced weight and costs have been achieved with press technology including thickening of the necessary parts for strength.
Super thin cross section and low friction have been achieved.
High capacity and high moment rigidity have been achieved by increasing the limited number of balls in the front row.
The cartridge bearing has little mechanical loss while requiring no preload setting.
High precision & lightweight plastic pulley bearing with creep prevention mechanism.
Optimum timing belt tension has been achieved with a multi-disc damper adjusted to various engine specifications.
FAQs
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.
While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.
Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings. NMT uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
