Crossed Roller Slides

Crossed roller bearings are widely used in precision systems due to their high rigidity and smooth motion. Their crossed roller arrangement improves load capacity and stability.

Choosing the right bearing requires evaluating performance, space and durability. Factors like cage type, travel limits and wear resistance all influence reliability, especially in demanding applications.

SoIving Precision Manufacturing Pain Points with STUDROLLER Technology

Motion control systems are commonly challenged with vibration, misalignment and premature wear issues, particularly in high-speed and/or high-load environments.

Engineered with rollers that distribute loads over a larger surface area, NB’s STUDROLLER technology addresses these... Read more...

First, what are the application requirements?

• Machine type that will activate the bearings
• Space needed in the equipment
• Environmental conditions
• Desired accuracy

STEP 1.Determine which type of bearing system should meet the requirements, i.e. slide guides, ball splines, round shaft products, slide shafts, slide ways including tables,... Read more...

Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bearings. And unlike ball bearings, they can support moment loads, radial forces or tilting loads. This lets one crossed roller bearing replace more than one ball bearing, thus saving the space required by ball bearings, lo... Read more...

Is This The Linear Motion Component You’re Using For Wafer Manufacturing

We're not referring to linear bearings that incorporate ball bearings - meaning friction is reduced between moving parts by recirculating (usually metal) balls. We're referring to the bearing most in demand for movement that requires the highest degree of precision - such as microprocessor... Read more...

The Innovative anti-cage creep STUDROLLER™ System developed by NB - Nippon Bearing eliminates cage creep completely.

The NB NV and NVT types crossed roller slide guide and table comprise precisely ground rails and R-retainers with built-in STUDROLLERs and precision rollers. The rails have been optimally designed so that the STUDROLLERs move smoothly, and the STUDROLLERs and... Read more...

Of course crossed roller bearings provide more linear motion accuracy, rigidity, and weight-bearing capacity than other friction-reducing devices such as ball bearings – plus they support greater radial forces, moment or tilting loads. One crossed roller bearing replaces multiple ball bearings, saving space and costs. The best crossed-roller slideways, allow under 2 microns deflect... Read more...
