Product catalog summary

SBI High-load Linear Rail System Overview

This document provides comprehensive technical data for the SBI series of high-load linear rail systems, designed for precision linear motion with high load capacities. It covers product models, mechanical parameters, rail specifications, lubrication, accuracy, tolerances, preload options, seal types, and ordering information.

1. Product Models and Dimensions

The SBI series includes multiple models such as FL/FLL, SL/SLL, HL/HLL, FV, CL/CLL, and SV, each with distinct block and rail designs. Key dimensional parameters include height, width, length, mounting hole sizes, grease fitting types, and bolt sizes, all specified in millimeters. Side grease nipple holes are custom-built upon order to prevent contamination.

Model-specific block and mounting dimensions facilitate application-specific selection.
Grease fittings and bolt sizes vary by model for maintenance and installation.

2. Load Ratings and Mechanical Parameters

Load ratings are provided as basic dynamic (C) and static (Co) values in kilonewtons, along with permissible static moments (Mro, Mpo, Myo) in kN·m. Mass data for blocks and rails assist in system weight calculations. Larger models support higher loads and moments. Maximum rail lengths are specified, with butt joints available for longer rails.

Load and moment ratings ensure safe and reliable design.
Mass data supports accurate system weight estimation.
Rail length customization available via butt joints.

3. Rail Specifications and Maximum Lengths

Bottom mounting rail types (SBI-B) have standardized dimensions including width, height, bolt hole size, and pitch. Maximum rail length is generally 4000 mm, with custom lengths and bolt hole sizes available. Weight per meter is specified for handling considerations.

Standardized rail dimensions ensure compatibility.
Custom rail lengths and bolt hole sizes can be requested.
Weight per meter data aids in logistics and design.

4. Grease Fittings and Lubrication

Standard grease fittings include front and side types with model-specific thread sizes (M4x0.7P, M6x0.75P, PT1/8). Various grease fitting models and nipple connectors are detailed for compatibility. Side grease fittings are custom-built to avoid contamination. Copper pipe connectors are available for certain models to facilitate lubrication.

Proper lubrication is critical for system longevity and performance.
Custom side grease fittings prevent contamination.
Copper pipe connectors enhance lubrication options.

5. Accuracy and Tolerances

Accuracy classifications include Normal, High, and Precision, with associated shoulder heights and fillet radii. Dimensional tolerances are specified for height (H), rail-to-block lateral distance (W2), and differences among blocks, ranging from 0.1 mm (standard) to 0.02 mm (high precision). Running parallelism between key surfaces ensures precise alignment.

Strict tolerances guarantee high precision and interchangeability.
Parallelism maintained between critical surfaces for alignment.

6. Preload Specifications

Preload options relative to the basic dynamic load rating (C) include:

K0 (None): Clearance within 0.01 mm
K1 (Normal): 0.00 to 0.02 × C
K2 (Light): 0.04 to 0.06 × C
K3 (Heavy): 0.08 to 0.10 × C (not available for SBI15)

These options allow customization of rigidity and clearance based on application needs.

7. Block Dimensions and Features

Fillet radius and shoulder heights vary by model number, with detailed dimensions provided for models 15 through 65. These features influence block strength and mounting compatibility.

8. High Temperature (HT) End Plates

HT end plates replace plastic components with steel or aluminum to withstand elevated temperatures. Side grease fittings are not available for HT end plates. Reference dimensions and compatibility with SBI models are provided.

9. Seal Resistance and Grease Specifications

Seal resistance values (in Newtons) for different end seals (DF, MF) are specified per model, indicating maximum seal resistance without grease. Scrapers have no resistance as they do not contact the rail.

10. Seal Types and Ordering Information

Seal types include end seals (E), scrapers (S), DF (high dust protection), and MF (self-lubricating). The bottom seal is integrated with the bottom retainer except for SBI15. When MF containers are used, grease fittings are omitted unless side grease fittings are ordered separately. Ordering examples illustrate model number construction including block quantity, preload, rail length, accuracy, and grease type.

11. Dimensions of Seal Components and Accessories

Dimensions for RC cap seals and MF containers are provided, with RC 30 specifically used for SBI 30 and 35 rails. ST tape dimensions are also listed, with consistent thickness of 0.1 mm.

12. Overall Lengths with Seals

Overall block lengths with various seal configurations are detailed, showing how seals affect total length. Seal combinations include single end seals, scrapers, DF, MF, and their combinations, critical for precise assembly and integration.

Summary of Critical Information

Multiple SBI models address diverse load and dimensional needs.
Load ratings and permissible moments ensure safe design margins.
Standardized yet customizable rail lengths and mounting dimensions.
Specified lubrication fittings and grease options maintain performance and prevent contamination.
Accuracy classes and strict tolerances support high precision applications.
Preload options enable adjustment of rigidity and clearance.
High temperature end plates enhance durability but limit grease fitting options.
Seal resistance data guides optimal seal selection for protection and lubrication.
Comprehensive ordering codes and dimensional data facilitate accurate specification and procurement.

This detailed technical information supports engineers and designers in selecting, specifying, and implementing SBI high-load linear rail systems for industrial automation and precision motion applications.
