Description

NSK WBK04R-11 belongs to ball screw support, part of our Linear motion range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for WBK04R-11 and any equivalents.

A ball screw support unit holds the screw in place and takes the axial forces in precision machinery. The NSK WBK line appears in machining centers, milling and grinding machines, and automation equipment where axial rigidity and repeatable positioning matter. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in Latin America.

Reading a WBK code is the quickest way to narrow down a support unit. Take WBK04R-11 and WBK06R-11: the digits right after WBK give the nominal screw diameter, so 04 means 4 mm and 06 means 6 mm. The R tells you the mounting configuration, and the -11 ending marks a particular construction variant in the series. Match those three pieces of information against your screw diameter and the fixing style your machine uses.

These units suit ball screws on machine tools, coordinate tables, linear actuators and positioning systems that demand accuracy. You will see them in machine shops, automation plants and operations that build special-purpose equipment. The WBK range includes mountings with angular contact bearings and built-in sealing, which keeps assembly simple and cuts the adjustment work needed at the machine.

Selection comes down to three inputs: screw diameter, axial load and the tilting moment the unit has to resist. During installation, line the support up with the linear guide and set the preload to the specified clearance. Lubrication and sealing in good condition keep contaminants out. When the screw is already known, the matching WBK code gives you dimensional interchangeability.

Support units from different manufacturers frequently share standardized dimensions, yet tolerances and preload are not always the same. On a replacement job, verify the mounting interface and the load capacity before ordering. If all you have is another brand's code or a part you cannot identify, send it to us on WhatsApp and we will point you to the equivalent for your equipment.

MR Industrial Accessories LLC supplies the NSK line. Send the WBK code or your screw measurements by WhatsApp or email and the team will reply promptly with the unit you need, and can suggest equivalents or help you choose.

Frequently asked questions

How do I work out which WBK support unit I need?
The code carries the nominal screw diameter and the mounting type, so WBK04R-11 fits a 4 mm screw. Check the diameter and configuration on your machine, and send us the details on WhatsApp if anything is unclear.
Where are NSK ball screw support units used?
They are found on machining centers, milling machines, grinding machines, coordinate tables and automation systems that need high axial rigidity and repeatability, both in metalworking shops and in precision equipment manufacturing.
How do I get a quote for a WBK support unit from MR?
Message us on WhatsApp with the WBK code or the screw measurements. We will quote the NSK unit you need and answer promptly. If you only have another brand's code, we can also identify the equivalent.
