SPG / SPS Spacer Linear Rail System

Product catalog summary

Overview of SPG / SPS Spacer Linear Rail System

The SPG and SPS spacer linear rail systems are designed with ball spacers inserted between balls to minimize noise by eliminating metal-to-metal contact. These spacers also retain grease, enabling long-term, maintenance-free operation. The systems use SBG standard rails and are dimensionally interchangeable with SBG/SBS blocks, facilitating easy replacement or integration.

Design Features

Ball Spacer: Inserts between balls to reduce noise and wear.
Grease Retention: Spacers store grease, enhancing lubrication and reducing maintenance.
Compatibility: Uses SBG standard rails and interchangeable with SBG/SBS blocks.
Ordering: Ordering procedures for SPG/SPS types are identical to SBG types.

Noise Level Performance

Noise level tests comparing SBG35 and SPG35 at 1.3 m/sec show the SPG type achieves reduced noise due to the spacer design.

Technical Specifications and Dimensions

The document provides detailed dimensional data and load ratings for various SPG and SPS models, including FL/FLL, SL/SLL, HL/HLL, FV, and SV types. Key parameters include mounting dimensions, block dimensions, mounting tap hole sizes, grease fitting types, and bolt sizes.

Load Ratings and Mass

Basic Dynamic Load Rating (C): Ranges from approximately 12 kN to 46 kN depending on model and size.
Basic Static Load Rating (Co): Ranges from approximately 17.5 kN to 90.4 kN.
Permissible Static Moments (Mro, Mpo, Myo): Provided for each model, indicating load capacity in different directions.
Mass: Block weights range from about 0.12 kg to 1.24 kg; rail weights range from 2.2 kg/m to 6.4 kg/m.

Mounting and Grease Fittings

Mounting holes and bolt sizes vary by model, with common bolt sizes including M5, M6, M8, and M10.
Grease fittings are typically M6x0.75 with a 6 mm diameter hole; side grease nipple holes are not pre-made to prevent contamination and are custom-built upon order.

Model Variants

SPG-FL/FLL: Bottom mounting type blocks with detailed dimensions and load ratings.
SPG-SL/SLL: Side mounting type blocks with smaller widths and heights.
SPS-SL, HL/SLL, HL: Variants with different block heights and widths, suitable for various applications.
SPS-FV and SPS-SV: Compact block types with lower heights and lengths, suitable for limited space applications.

Critical Notes and Recommendations

The side grease nipple hole is not pre-drilled to prevent foreign substance ingress; it is manufactured upon request.
All models have a maximum rail length of 4000 mm.
Dimension interchangeability with SBG/SBS types allows for flexible system design and replacement.
Grease retention by spacers supports long-term maintenance-free operation, improving system reliability.

Summary

The SPG/SPS spacer linear rail systems offer enhanced noise reduction and maintenance benefits through their ball spacer design and grease retention capability. They maintain compatibility with standard SBG rails and blocks, providing flexibility in design and ordering. Detailed dimensional and load specifications support precise engineering selection for various linear motion applications.
