Now, Keshav Industries has extended its innovative ideas in a new range of products which are playing a critical role in drafting system on Spinning and Speed Frames of all models, similar drafting system like SKF, Suessen, INA,Reiter, Lakshmi, WST etc.

While developing the above said Top rollers for drafting system which is useful in Spinning and Speed Frames of various models, Keshav Industries has incorporated many special features to improve the quality of the product in all respects. Even the quality of the Yarn at end user side through this product will be excellent for a longer duration with consistency.

Special Features:

Shell: 
It is made out of alloy steel with high Chrome and medium Carbon. Optimum level hardness introduced to a particular depth at bearing seating area to take care of wear & tear.Provision is made for the passage of lubricant to the bearing in the Shell.

Boss:
It is made out of alloy steel with medium Carbon and toughend through heat treatment process to withstand for load factors. The Boss is assembled with Needle Bushes consists of a thin, heat treated outer ring formed from accurate controlled sheet steel encasing a set of needles. By this, the load factor comes on this Boss will have uniform distribution at wider area and leads for concentric running of the Boss on the Shell for very long period and there is no scope of having wear & tear on the Shell at shorter duration.

Guide Bush - Thrust Pad - Locking screw:
By introducing these items in assembly, the provision is made to detach the Boss from the Shell whenever needed. To take care of the thrust load factors and to avoid the micro dust entry in bearing chamber, Guide Bush and Thrust Pad have been given at either side of the Needle Bush with off set locking system through Locking Screw. Having this arrangement, the axial play of the Boss on the Shell can be adjusted to a precise level.

End Cap: 
It is made out of Nylon material. It is being assembled at the end of the Boss to prevent micro dust entry in side the assembly zone. Provision is made to lubricate the system without dismantling the End Cap. Similar to Draw Frame Top Roller, before mounting the cot on the Boss, the run out of the Boss with respect to Shell to be confirmed well within the limits. Since the buffing of the Cot will be carried out through centreless buffing system, we have to confirm that the concentricity between inner diameter of the Cot with respect to outer dia. of the Cot should lie well within the allowable limit llike 0.005mm. 

By doing so, the drafting will be very precise.
