Here is the DOPPLER needle cage, it is a really specific product and quite unusual indeed DOPPLER is the only manufacturer to still offer needle cages with specific clearances for MBK 51. This cage is very high quality, ultra reinforced and with improved lubrication. Size like the origin and all other models Ø13 X Ø16 X L.14mm.
The Clearance must be selected according to the forcing on the piston pin but also according to the engine speed! Generally, with the example of a crankshaft bearing, we will take a cage with very little play for an engine which takes low revs because it does not require big freedom! However, on a very high speed engine, if the cage has very little play, at very high speed it risks entering into seizure / overheating phenomenon and risks yielding in addition to slightly restricting the engine speed.
-Game from 0 to - 2 (low and medium engine generally 0 to 9,500 rpm max)
-Game from - 2 to - 4 (high speed generally 9500 to 14,000 rpm max)
Remember to select the desired game before adding it to the cart.
