THK Linear Bushings / Linear Ball Bearings / Linear Ball Bushings

Type with LMF type flange having flats at 4 locations. Can be used in compact designs since the core height is lower than with the round flange type.

This linear bushing has an outer diameter formed by a highest-precision cylinder, and is used in a wide range of applications.Part of the milli series, the most widely used series in Japan.

The outer cylinder of the standard-type linear bushing and the flange are integrated and fitting is easily achieved by bolting directly to the housing.

This linear bushing has an outer diameter formed by a highest-precision cylinder, and is used in a wide range of applications. It is part of the milli size series, which is in general use in Europe.

The outer cylinder of the standard-type linear bushing and the flange are integrated and mounting is easily achieved by bolting directly to the housing.With 2 standard retainers embedded, this product is optimal for sites subject to moment loads.

The flange and outer cylinder are integrated and the flange is oval-shaped. This gives a lower core height, making this type more suitable for compact designs than the LMK type.To lengthen the product life, the balls of the linear bushing are embedded in two races to support the load from the flats.

Case unit has standard-type linear bushing embedded in small lightweight aluminum case. Can be mounted by simply bolting to table.

Hardened shaft, recommended for use with outer diameter tolerance (k5, m5, n5 or p5).[Features]· In the ST type, the balls and ball cage are embedded in the inner side the of outer cylinder, which has been precision ground to ensure a cylindrical form· The balls are arranged in a staggered form to that the load is equally distributed· The ball cage is a machined cage made out of lightweight and highly rigid light alloy.· A slide ring and retainer ring are provided on two sides of the internal diameter of the outer cylinder to prevent overrun of the ball cage.· With this structure, it is possible to achieve rotating, linear and mixed action with a low friction coefficient.· Stroke length can be up to double the range of movement of the ball cage within the outer cylinder· Suitable for a wide range of applications where it is necessary to obtain high accuracy at a low price, including the ink roll parts of a printing machine, the work chuck of a punching press work, press feeders, the work head of an electric discharge machine, the correction device of a take-up roll, textile machines, strain measuring equipment, optical measuring device spindle, copiers, etc.· Enables rotation with extremely low friction coefficient (=0.0006 to 0.0012) due to point contacts between the balls and ball rolling surface, and the separation of the balls within the ball cage.· Since the cross-sectional profile is simply the combination of the thin-walled outer cylinder and the balls, the outer diameter of this bearing is small and it is suitable for lightweight and space-saving compact designs.

With 2 standard retainers embedded, this product is optimal for sites subject to moment loads and reduces assembly time.

Type with LMF-L type flange having flats at 4 locations. Due to a lower core height, this type is more suitable for compact designs than the round flange type.

Hardened shaft, recommended for use with outer diameter tolerance (k5, m5, n5 or p5).[Features]· [Extremely low friction coefficient] Enables rotation with extremely low friction coefficient (=0.0006 to 0.0012) due to point contacts between the balls and ball rolling surface, and the separation of the balls within the ball cage.· [Compact-design] Since the cross-sectional profile is simply the combination of the thin-walled outer cylinder and the balls, the outer diameter of this bearing is small and it is suitable for lightweight and space-saving compact designs.· [High accuracy and low price] The sliding parts can be manufactured at low cost and a high level of accuracy is obtained.

[Features]· Pilot flange type linear bushing.· Available in 3 types, round, rectangular and round with chamfering. Each of these is also available as a long type.

Flange is oval-shaped. More suitable than the LMK-L type for compact designs due to lower core height.With 2 standard retainers embedded, this product is optimal for sites subject to moment loads.To lengthen the product life, the balls of the linear bushing are embedded in two races to support the load from the flats.

[Features]· Standard type. Equivalent to LM type of widely used milli size series, but including metal retainer.

This linear bushing has an outer diameter formed by a highest-precision cylinder, and is used in a wide range of applications. Part of the milli series, the most widely used series in Japan.

[Features]· Linear bushing of center flange type.· Available in 3 types, round, rectangular and round chamfered. Each of these is also available as a long type.

Optimal if enhanced dust-proofing is required, or if the seal resistance is to be reduced.

Type with LMF type flange having flats at 4 locations. Can be used in compact designs since the core height is lower than with the round flange type.

Type with LMF-L type flange having flats at 4 locations. Can be used in compact designs since the core height is lower than with the round flange type.

SC long type. The case unit has 2 standard type linear bushings embedded in an aluminum case.

Case unit is based on LM case unit SC-type with standard linear bushing embedded in small lightweight aluminum case. Compared to the SC type, this type is more suited for compact designs. Any mounting direction is acceptable and lifetime performance is enhanced due to 2 races of load-bearing balls on the case upper face.

The outer cylinder of the standard-type linear bushing and the flange are integrated and mounting is easily achieved by bolting directly to the housing.With 2 standard retainers embedded, this product is optimal for sites subject to moment loads.

SH long type. The case unit has 2 standard type linear bushings embedded in an aluminum case.

[Features]· Uses high-strength reinforced plastic in flange portion to achieve a reduction in weight compared with the conventional metal flange type (maximum 25%)· Contributes to weight reduction when mounted to movable parts.· Reasonable price realized by replacing the metal of the reasonably priced flange with high-strength plastic.
