With its profitable observe file within the rail business, NSK has developed a brand new vary of drugs bearings, additional enhancing the extent of security in older technology merchandise. Can be utilized to assist each giant and small transmissions in railway gearboxes, these bearings are perfect for excessive and low velocity functions.
NSK’s bearings for small gear shafts mark a brand new period in worth added with greater security and fewer upkeep necessities. NSK’s bearings for giant gear shafts additionally present a excessive stage of security. It has expanded its requirements to cowl totally different sizes with a purpose to meet buyer wants.
Reducer bearings function underneath extreme situations underneath the vibrations and impacts of the wheels transferring on the rails. Such harsh situations make common upkeep of bearings a necessity, which implies elevated workload. The meeting, upkeep operations of tapered curler bearings used to assist gears and pinion shafts, and the adjustment of the suitable bearing clearance are very tough duties that may be accomplished by skilled upkeep engineers. These operations improve the price of possession (TCO) of the railroad corporations and trigger severe time loss and workload.
NSK has developed new bearings incorporating proprietary applied sciences, considering the upper security calls for towards these challenges. The general good thing about NSK improvements is to considerably enhance meeting (small gear bearings solely), prolong upkeep intervals, and contribute to decreasing TCO.
Its design, which permits low upkeep prices, is among the many most elementary options of the bearings utilized in small gear shafts. The mix of latest cylindrical bearings and four-point contact ball bearings simplifies meeting and upkeep by eliminating the necessity for bearing clearance adjustment. NSK ships these bearings with predetermined clearances, thus guaranteeing extremely optimized outcomes. One other enchancment is expounded to cage energy, which is significant the place there may be intense influence and vibration. NSK has developed a ring-guided cage with optimized pockets with ‘R-shaped’ corners. This distinctive design reduces stress within the cage construction by 75%.
The brand new bearings for small gears additionally characteristic a specifically heat-treated interior ring to make sure dimensional stability even underneath long-term use at excessive temperatures. Very excessive dimensional stability prevents the bearings from sliding alongside the shaft by stopping friction.
For the high-safety tapered curler bearing collection utilized in giant gear shafts, NSK has added many new customary sizes to its product vary to satisfy the growing calls for. Rail automobile producers can rapidly and simply provide these broadly examined customary bearings of their new designs. Manufactured with over a century of experience, confirmed high quality and reliability, NSK rail bearings are the merchandise most well-liked by the most important rail operators in additional than 20 nations.
