SLIDE WAY SLIDE TABLE MINIATURE SLIDE GONIO WAY

Product catalog summary

Overview
The document provides comprehensive technical specifications and guidelines for various types of slide ways, including NV, SV, SVW, and GONIO types, used in precision equipment for high accuracy and stability.

Slide Way Structure and Advantages
The NV type features precisely ground rails and R-retainers with STUDROLLERs and precision rollers for smooth, slip-free operation. SV and SVW types use precision caged-rollers to minimize frictional resistance fluctuations. The STUDROLLER system prevents roller cage slippage, allowing usage in all orientations.

Types and Specifications
The NV slide way includes four rails, two R-retainers, and eight end pieces for flexible table design. The NVS-RNS type is stainless steel for anti-corrosion and high-temperature environments. The SV type has four rails and precision rollers in a cross arrangement, with an all-stainless steel option for corrosive environments.

Performance Characteristics
Designed for minute motion with high accuracy, low-speed stability, high rigidity, and high load capacity. The NV type offers a load rating 1.3 to 2.5 times that of the SV type, ensuring low noise and availability in stainless steel for clean room applications.

Accuracy and Load Rating
Accuracy is classified as high, precision, or ultra precision, measured as parallelism across the full length. Load ratings vary with load direction, with specific equations for calculating rated life and load ratings.

Installation Procedures
Detailed procedures for NV and SV types emphasize careful handling, proper alignment, and preload adjustment for optimal performance and longevity.

Lubrication and Dust Prevention
Pre-lubricated with lithium soap-based grease, requiring periodic relubrication. Dust prevention measures are recommended in harsh environments to maintain motion accuracy and extend lifespan.

Use and Handling Precautions
Careful handling is crucial to prevent damage. Fastening plates maintain the R-retainer's center position before assembly. Exceeding specified stroke lengths or excess preload can damage components.

Operating Conditions
The NV type should be used below 80°C due to resin parts. Rails are matched within each set for accuracy, and combining different sets can affect accuracy. The allowable load ensures smooth rolling movement, with potential cage slippage under high stress in SV/SVW types.

Specifications and Recommendations
Guidelines for installation and maintenance under various conditions, emphasizing stroke margin and avoiding excessive preload. Cycling the rails to perform the maximum stroke ensures the cage returns to its central position.

End Pieces and Knock Pin Hole
End pieces prevent cage removal and should not be used as mechanical stoppers. For SVW type, machining knock pin holes should be done after attaching the W type rail, followed by thorough cleaning.

Installation Procedure for Special Mounting Screw BT Type
Involves cleaning the rail-mounting surface, applying low-viscosity oil, attaching rails with recommended torque, inserting roller cages, and adjusting preload. Detailed steps with figures emphasize not applying excessive preload.

Torque Specifications
Tables provide recommended torque values for adjustment and mounting screws, with specific values for different screw sizes and part numbers.

Special Mounting Screw Details
Specifications for special mounting screws, including dimensions and applicable sizes, made of alloy steel with custom stainless steel versions available.

Slide Way Specifications
Details various slide way types with specifications such as rail length, number of rollers, accuracy grades, and load ratings, including part number structures and dimensions.

Load Ratings and Dimensions
Tables provide dynamic and static load ratings, allowable loads, and major dimensions for different slide way sizes and configurations, including anti-corrosion specifications and special environments types.

NB Miniature Slide SYBS Type Overview
Specifications and guidelines for the NB miniature slide SYBS type, a compact slide table for precision applications, including dimensions, load ratings, mounting instructions, and handling precautions.

NB Gonio Way RVF Type Overview
The NB Gonio Way RVF type is a precision curved cross roller slide way for high-precision optical and measurement equipment, featuring low-friction, non-recirculating precision rollers.

Specifications and Structure
Consists of curved tracking bases with precisely ground V-grooves and flat installation surfaces, ensuring low frictional resistance, high rigidity, and high load capacity.

Advantages

Low Frictional Resistance
Low Noise
High Rigidity and Load Capacity
Flat Installation Surface
Same Rotation Center

Accuracy and Measurement
Accuracy determined by mutual dimensional errors of four rails, with tables providing accuracy units in micrometers for various part numbers.

Installation Procedure

Remove burrs and dust from installation surfaces.
Apply low viscosity oil to contact surfaces and temporarily tighten screws.
Align reference edges and insert curved roller cages.
Secure the table and adjust screws with a torque wrench.
Ensure parallelism and secure mounting screws sequentially.

INSTALLATION PROCEDURE OF NV TYPE Please contact NB for a non-standard stroke length for the NV type. When the stroke of SV type or SVW type is changed, the stroke length must be determined and the load rating should be re-estimated as follows. Stroke of SV type, SVW type When the slide way moves along the rail, the cage moves half the distance traveled by the slide way in the same direction. Therefore, although the work may be fixed on the table, the distance between the load center and the cage center will change. To achieve stable accuracy, determine the stroke and the length of the rail as...

SLIDE WAY INSTALLATION PROCEDURE OF SV TYPE Installation Procedure SPECIAL MOUNTING SCREW BT TYPE Figure G-14 Installation Method In case of mounting slide way by screws from the counterbore side, threaded holes become the pilot holes. Thus, pilot hole's clearance will be less than a standard clearance hole for a screw. NB offers reduced shoulder screws for mounting SlideWay from bottom when larger screw clearance is required due to preload adjustment or inaccuracy of mating threaded holes. This special mounting screw made of alloy steel is stocked, and custom stainless steel version is available...
