We are engaged in manufacturing of Keyless Transmission Element  in accordance to various industrial standards. Our range of locking elements effectively reduces the torque that is formed by tightening the screw. These products are manufactured using the latest technology under expert supervision and are available for our clients at industrial leading prices.

Features:
Torque transmission : high. Self centering. Low installation time. The concentricity varies from 0. 02 mm to 0. 04 mm (t. I. R). Interchangable with model n7012. During installation, model n7013. 0; 7030; 7032; 7139 have slight axial displacement of hub in respect of shaft, when tightening clamping screws. Application economically advantageous.

Installation:
Taper locking elements are supplied ready for installation. Unscrew all screws by 2 or 3 turn. Transfer 2 or 3 screws symmetrical opposite in the tapped holes providing in inner ring, slightly tight to separate inner & outer ring to make insertion easier. Carefully clean the hub and shaft contact surfaces and apply a light oil film. Slide the clamping unit into hub bore & onto shaft. Reposition the transfered screws in holes as was. Tighten all clamping screws gradually and regularly, using torque wrench, in crossed sequence, in several pass, until the tightening torque (as per screw size indicated) is reached. The screws close to slit, should be tightened fully last to avoid deformation in the inner / outer rings. Repeat above mentioned operation till no one screw turn more.

Note: The tightening torque values indicated is valid only in case of slight oil lubricated assembly installation. Do not use any oil with molybdenum bisulphide or high pressure additives. 2. Installation subject to corrosion,the slits should be sealed with a suitable caulking compound or rust preventives.

Removal:
Important: Make sure the ends of screws used for removal are ground flat and slightly chamfered to eliminate damage to screw and removal threads loosen the clamping screws. Insert (2-3)removal screws into tapped holes provided in inner ring and tighten gradually in crossed sequence, till the assembly is released. If the assembly is to be reused, re-lubricate inner / outer ring, screws and reassemble, reuse or store.

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