Precise Needle Roller Pin

Precise Needle Roller Pin are simple a stationary base and a moving carriage low-friction motion high load-carrying capacitie

1)M/V Roller Pin Guide Rail and Block set:

M/V style, which have roller pin cage, fits for the high preloading Comparing with other similar ones, LB Roller Pin cage makes it smaller resistance, but high rigidity;

2)N/O Roller Pin Guide Rail and Block Sets

The rollers are crossed at a 90° angle in an alternating fashion and are enclosed in the rails, which have a machined V-shaped groove to support the rollers. Crossed roller slides resemble ball slides, but provide higher load-carrying capacities and can absorb greater load impacts. Most crossed roller slides have an aluminum carriage and base, steel rods and rollers, and stainless steel end caps. The rollers move between a set of smooth, flat, parallel rods on each side of the base. Although crossed roller slides are not self-cleaning, they are suitable for environments with low levels of dust and other airborne contaminants. Typically, crossed roller slides are more expensive than ball slides. 

Specifications for crossed roller slides include linear travel, dynamic load-carrying capacity, maximum linear velocity, and physical dimensions. Linear travel is measured in inches (in), feet (ft), millimeters (mm), or centimeters (cm). Dynamic load-carrying capacity is measured in ounces (oz), pounds (lbs), grams (g), or milligrams (mg). Maximum linear velocity is the speed at which the positioning carriage moves. Units of measure include inches per second (in/sec), feed per second (ft/sec), millimeters per second (mm/sec), and centimeters per second (cm/sec). Physical dimensions for crossed roller slides include base length, base width, top height, carriage length, and carriage width. Base length is the length of the base measured parallel to the main axis of travel. Base width is the width of the base measured perpendicular to the main axis of travel. Top height is the height of the unit from the base to the top of the carriage. Carriage length and carriage width are, respectively, the length and width of the carriage measured parallel to the main axis of movement. 

Crossed roller slides differ in terms of applications and features. Products that are certified for cleanroom environments are specified according the number of particles per million and the average particle size. Products that are design for vacuum environments are vacuum-rated. Some crossed roller slides include way covers or bellows to protect the rails and guides against the ingress of dust and dirt. Others include wipers or scrapers for cleaning the surfaces of rails and guides. Stackable slides or stages provide linear motion in more than one axis. Locks can be used to slow or stop linear motion, or maintain a specific carriage position. Double-carriage crossed roller slides are also available
