South India Bearing Co. handles NSK bearings in Chennai, including spindle bearings, ROBUST angular contact bearings, ball screw support bearings and industrial ball and roller bearings. Browse the product explanations, series references and manufacturer catalogues, then send the complete designation for a quotation.
NSK super-precision angular contact bearings support precision rotating assemblies. The catalogue covers 70, 79 and 72 families alongside specialised spindle bearing ranges. Each complete designation identifies further design details.
Include the contact angle, precision class, preload and matched-set markings specified in the requirement. A basic bearing number alone can omit important purchasing details.
ROBUST is NSK’s named range of super-precision angular contact bearings. BNR and BER references appear in the manufacturer’s machine tool bearing catalogue. The full code distinguishes the requested variant within that range.
Copy the complete designation, including cage, material, seal and arrangement suffixes where present. Do not treat the ROBUST name as a complete order specification.
Ball screw support bearings provide bearing support for screw-drive assemblies. NSK’s super-precision catalogue includes TAC angular contact thrust bearing references for these requirements. These bearings have a different role from the screw shaft and nut that transmit feed motion.
Send the complete TAC designation and assembly details from the parts list, including the specified arrangement and quantity. Keep the existing suffixes rather than substituting a general bore-size description.
NSK’s precision range also includes cylindrical roller bearings for spindle assemblies. The catalogue contains N and NN family references, with double-row NN designs among the documented products.
Preserve the full reference, bore configuration, precision and clearance markings from the approved specification. The precision catalogue provides model-specific drawings and designation information.
The industrial bearing catalogue covers ball and roller bearing families beyond spindle products. Different bearing constructions serve different equipment arrangements; the exact manufacturer reference identifies the requested component.
Include the make, full bearing code, closure, cage and clearance suffixes where specified, together with quantity. Use the rolling bearing catalogue for product dimensions and design information.
These are family references. The complete designation, including suffixes and matched-set markings, identifies the purchase requirement.

Machine tool spindles and screw-drive assemblies perform different functions. Spindle bearings support rotating spindle arrangements; ball screw support bearings form part of the support for the feed screw. The equipment specification identifies the bearing family, arrangement and preload required.
For a replacement enquiry, a readable label photograph or machine parts-list reference helps preserve the complete product marking. Include all set and suffix information with the requested quantity.
ROBUST identifies a named NSK super-precision angular contact bearing range. BNR and BER family references are included in the catalogue. The full model code is still needed to identify an individual bearing.
They are separate catalogue families. TAC references include angular contact thrust bearings for ball screw support requirements. Use the equipment specification and complete designation rather than assuming that a similar bore size makes them equivalent.
A precision bearing requirement can identify bearings supplied for a specified arrangement or set. Include the original set reference, preload and quantity; avoid shortening the marking to the basic size number.
Kindly send the full designation, quantity and delivery requirement. For spindle bearings, include precision, preload and set markings. For TAC bearings, include the full thrust-bearing reference and specified arrangement.
Use the NSK super-precision and industrial catalogues below for dimensions and designation details. NSK also provides individual product information such as its NN3017 double-row precision cylindrical roller bearing reference.
Share the part number or series, preferred quantity and delivery location. For a replacement enquiry, you can include the existing product marking or a photograph.
