CROSS ROLLER GUIDE
NEWSLIDE WAY HV Type
Evolutionary Cross Roller Guide HV Series Achieving High Rigidity, High Load Capacity, and Compact Design.
Features
The NB Cross Roller Guide HV Series and HVW Series are upgraded products with improved performance by reconsidering the design aspects such as the length of the raceway contact and roller pitch compared to SV, SVW series. In comparison with previous models, the allowable load capacity and rated life distance have been increased. Installation is fully compatible with SV, SVW series, contributing to the improvement of rigidity and durability of equipment and facilities simply by replacement. This enables downsizing and compactness while maintaining equivalent performance.
Installation is fully compatible with previous model
It is fully compatible with the conventional SV and SVW series.
Improved rigidity and durability by simple replacement
Due to its full compatibility with the SV and SVW series, installation is as simple as replacement, contributing to the improvement of rigidity and durability of equipment and facilities.
Allows downsizing and compactness while maintaining equivalent performance
Replacing with HV and HVW series enables reducing unit height, width, and overall length.
High rigidity and high load capacity
The rollers have a larger contact area compared to steel balls, resulting in reduced elastic deformation. Furthermore, due to the non-circulating design, there are more effective rolling elements, leading to high rigidity and high load capacity. Additionally, the HV series achieves an increase in the contact length between the rollers and the raceway groove by 30-58% compared to the SV series through a new rail design (refer to Figure A-2). Moreover, by refining the roller pitch and increasing the number of rollers, the rated load capacity has been increased by 1.3 to 2.5 times.
Extended contact length between the rollers and the raceway groove
Extending the contact length reduces the surface pressure generated on the rollers and the rails compared to previous design.
Narrower roller pitch
Narrowing the roller pitch leads to an increase in the number of rollers.
Type
HV Type
The HV slide way consists of a set of four rails, two RH type roller cages which hace precision rolers in a cross arrangement, and eight end pieces. The all stainless option(HVS type) makes it suitable for use in corrosive environment.
HVW Type
The HVW slide way consists of two HV-type rails, one W type rail, two RH type roller cages, and eight end pieces. The use of a W-type rails serves for a compact design. The HVWS type is also available with all stainless steel components.
