Shrink Disc

Item Code: N4091
We are offering Keyless Transmission Element (N4091) that is manufactured using quality raw material and latest technology. These Keyless Transmission Element (N4091) are appreciated by the clients for precision engineering, stable, anti-corrosive properties and good compressive strength.

Features:
Torque transmission : n 4091 - high-very high. N4071- medium. N4051 - low. No axial movement of hub. Even pressure distribution. External clamping. Develop concentric & well balanced connections. Low installation time. Application economically advantageous.

Installation:
Carefully clean the hub and shaft & other contact surfaces and apply a light film of molikote 321r or molikote g rapid or equivalent grease for taper seat & molikot br2 or equivalent grease for bolts. Slide the shrink disc assembly onto the hub & hub onto the shaft. Tighten clamping bolts lightly & align hub. Tighten all bolts gradually and regularly in clockwise sequence in several pass, using torque wrench, until the tightening torque (as per bolt size indicated) is reached. Check all the bolts for the tightening torque, repeating above mentioned operation, till no bolt turn more.

Note: The tightening torque values indicated is valid only in case of oil installation. 

Tolerances, surface finish:
A good surface finish by machine tool is sufficient. Maximum allowable surface finish : rt max 16um (0. 016mm). Maximum permissible tolerances for hub h8 & for shaft h8.
