Support Units (Compact type)

Product catalog summary
Overview: The document discusses KSS Compact Support Units for Miniature Ball Screws, emphasizing their compact and lightweight design suitable for clean environments. These units offer various configurations to accommodate different installation requirements.
Specifications: The support units feature pre-load controlled Angular Contact Bearings made from stainless steel with low contamination grease, ensuring high rigidity. They are available in ultra-compact sizes, including a new φ3 series, and come in Pillow and Flange types, standardized for both fixed and supported sides.
Features: Key features include minimized mounting hole pitch for compactness, high rigidity through pre-load controlled bearings, cost reduction by eliminating oil seals, and the use of stainless steel components. The units are designed for clean environments and offer a wide variety of choices with standardized Pillow and Flange types.
Variations: The document details the available variations, including Pillow and Flange types, and notes that conventional Block type units are still available. The units are compatible with standard end-journal profiles of KSS Miniature Ball Screws.
Model Number Notation: The document explains the model number notation, detailing the series number, nominal number, housing type, and end-journal type.
Bearings: The support units use Angular Contact Ball Bearings for the fixed side and Deep Groove Bearings for the supported side, designed for clean room use, made from stainless steel, and packed with low contamination grease.
Mounting Procedure: A step-by-step guide is provided for assembling the support units onto the ball screws, emphasizing not to disassemble the pre-loaded and pre-adjusted units.
1. Assembly of Shaft and Support Unit:
  • Insert the Shaft into the Support Unit and tighten the Lock-Nut. Ensure the set piece does not curl.
  • For the fixed end, tighten the Lock-Nut and secure it using the set piece and hexagonal socket head set screw.
  • Mount the supported end Bearing, secure it with the stop ring, and fit it into the Housing.
2. Mounting the Table and Ball Screw Nut:
  • Insert the Ball Screw Nut into the table or bracket and loosely tighten.
  • Loosely secure the fixed end Support Unit to the base. Center the table and adjust for smooth movement.
3. Mounting the Supported End Housing and Accuracy Check:
  • Move the table toward the supported end Housing, center it, and adjust for smooth movement. Secure loosely to the base.
  • Check the Run-out and Axial gap using a dial gauge, then fully tighten the Nut, fixed end Support Unit, and supported end Housing.
4. Connecting to the Motor:
  • Secure the Motor to the main Unit.
  • Connect the Motor to the Ball Screw using the coupling.
  • Conduct a thorough run-in.
Note: The instructions are for Pillow type Support Units, but the same procedure applies to Flange type Support Units.
