THK Linear Motion Guide Model HSR12RM, Double Block: 20mm Height, 27mm Width, 45mm Length, Rail: 11mm Height, 12mm Width, 110mm Length, 40mm Pitch

THK Linear Motion Guide Model HSR12RM, Double Block: 20mm Height, 27mm Width, 45mm Length, Rail: 11mm Height, 12mm Width, 110mm Length, 40mm Pitch Reviews

Other Picture

THK Global Standard Full-Ball LM Guide Model HSR. Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate. Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications. In addition, the LM block can receive a well-balanced preload, increasing the rigidity in the four directions while maintaining a constant, low friction coefficient. With the low sectional height and the high rigidity design of the LM block, this model achieves highly accurate and stable straight motion. Even under a preload or excessive biased load, differential slip of balls does not occur. As a result, smooth motion, high wear resistance, and long-term maintenance of accuracy are achieved.

• 4-way Equal Load Type
• Compact
• Lightweight
• Low Dust Generation
• End seal contamination protection accessory

Caged Ball LM Guide model SRS has a structure where two raceways are incorporated into the compact body, enabling the model to receive loads in all directions, and to be used in locations where a moment is applied with a single rail. In addition, use of ball cages eliminates friction between balls, thus achieving high speed, low noise, acceptable running sound, long service life, and long-term maintenance-free operation. Use of ball cages eliminates friction between balls and retains lubricant, thus achieving low dust generation. In addition, the LM block and LM rail use stainless steel, which is highly resistant to corrosion. Since the right and left rows of balls under a load contact the raceway at 45°, this LM Guide is capable of receiving loads in the radial, reverse radial and lateral directions at equal values and being used in any orientations. With this well-balanced structure, this model can be used in extensive applications. Since SRS has a compact structure where the rail cross section is designed to be low and that contains only two rows of balls, it can be installed in space-saving locations. Since part of the LM block is made of resin and formed through insert molding, SRS is a lightweight, low inertia type of LM Guide.

RBC Cam Follower S24LWX 0.750" Outside Diameter, Standard Stud Type, Hex Head, Sealed Cam Follower With Eccentric Outer Ring

RBC Cam Follower S24LWX 0.750" Outside Diameter, Standard Stud Type, Hex Head, Sealed Cam Follower With Eccentric Outer Ring Reviews

Other Picture

RBC Cam Follower S24LWX 0.750" Outside Diameter, Standard Stud Type, Hex Head, Sealed Cam Follower With Eccentric Outer Ring Feature

• Threaded stud for mounting convenience
• Eccentric collar design for applications where accurate positioning is critical
• Hex head design for ease of installation and high torque tightening
• Black oxide finish provides added corrosion resistance
• Double gap seals to keep contaminants out

This RBC cam follower is part of the RBC HexLube Universal line of cam followers. It can be relubricated through the hex head which can be a great convenience in tight spaces or when stud access is impossible. A cam follower that is properly maintained and lubricated will last longer than a cam follower that is neglected due to the difficulties posed by relubrication. The hex head feature is the preferred mounting method for stud-type cam followers, and with 2 gap seals to keep contaminants out, this RBC HexLube cam follower is the versatile workhorse of the needle bearing cam follower product line. This cam follower is designed with a feature that allows it to be adjustable. Adjustable cam followers can be used where accurate positioning is required and they are particularly useful for reducing clearance or backlash in opposed arrangements, and for assuring load sharing in multiple cam follower installations. RBC HexLube Universal Cam Followers are designed for applications such as automation and production equipment, bottling and canning, printing machinery, material handling, construction equipment, transfer lines, food processing, and packaging equipment. RBC Bearings has been providing bearing solutions to our customers since 1919. A publicly-traded company (NASDAQ: ROLL), RBC currently has 23 manufacturing facilities worldwide, with 18 located in the USA.

RBC Cam Follower Y24 0.750" OD x 0.2500" ID, Yoke Type (Without Stud), Unsealed Cam Follower

RBC Cam Follower Y24 0.750" OD x 0.2500" ID, Yoke Type (Without Stud), Unsealed Cam Follower Reviews

Other Picture

RBC Cam Follower Y24 0.750" OD x 0.2500" ID, Yoke Type (Without Stud), Unsealed Cam Follower Feature

• Yoke type design allows for clevis mounting which provides support on both sides of the cam follower and permits use of a high strength pin
• Internal needle roller configuration for moderate loads
• Considerably heavier cross section outer ring to reduce deformation under load
• Black oxide finish provides added corrosion resistance
• Unsealed for reduced rolling resistance

This yoke style RBC needle bearing cam follower is traditional in design, with a heavy outer ring cross section and a full complement of needle rollers. It offers high dynamic and static load carrying capability, and anti-friction performance, in a compact design. Yoke rollers are mounted with a pin in a yoke. Under load the pin is subject to shear and bending stresses. RBC recommends that the yoke arms are located as close to the yoke roller as possible. In case of widely spaced pin supports, the resulting pin deflection may cause yoke roller damage. RBC yoke rollers correspond in many respects to the same size cam follower, except they are mounted on a pin for use in yoke type applications for greater shock resistance. Yoke rollers should be clamped axially or mounted within closely fitting side rails to prevent displacement of the end plates. For applications with heavy loads, it is recommended to heat treat the pin and use a press fit for the inner ring. A soft pin and light press or push fit are sufficient for lightly loaded applications. When press fitting a yoke roller, pressure should be applied centrally and uniformly against the end plate, never against the outer ring. The pin should have a suitable lead-in chamfer or radius to prevent scoring and to hold the mounting force to a minimum. RBC Bearings has been providing bearing solutions to our customers since 1919.
