Part of the Roller range, used in Warehouse and Distribution Centres.

Key Benefits

  • Tapered roller design supports axial and radial loads in one direction
  • Nylong and PP housing reduces weight and provides low friction
  • Available with galvanized, chrome plated, PU or rubber coating for wear and corrosion resistance
  • Fits shafts with ø12 mm diameter and has a 3.6 taper degree for precise alignment
  • Mounts on steel or SUS304 tube material for use in industrial and clean environments

Application Scenarios

  • Conveyor systems requiring precise alignment and load support on a shaft
  • Assembly lines where components must be guided with minimal friction
  • Material handling equipment with rotating or sliding parts under axial load
  • Industrial environments where corrosion resistance is needed with galvanized or chrome plated options
  • Applications requiring surface protection with PU or rubber coating on the roller

Who It Is For

  • Conveyor system integrators needing precision rollers for guided movement
  • Industrial equipment builders designing components with axial load capacity
  • Material handling system designers requiring low-friction, durable rollers
  • Manufacturers of automated lines using guided shafts with precise alignment
  • Industrial distributors sourcing precision rollers with multiple surface options

Problems It Solves

  • Misalignment caused by radial and axial forces in rotating shaft applications
  • Excessive wear on rollers due to lack of surface protection in harsh environments
  • High friction in guided systems due to non-precision roller designs
  • Need for multiple roller types when a single design must handle both axial and radial loads
  • Difficulty in maintaining consistent roller performance across different environmental conditions

Technical Features

  • Tapered roller design with 3.6 degree taper for load distribution
  • Nylong and PP housing for lightweight and low-friction operation
  • Shaft diameter of ø12 mm for compatibility with standard shafts
  • Overall length of 11 mm and width of 11 mm for compact installation
  • Available with steel or SUS304 tube material for different strength and corrosion needs

Materials

  • Steel tube material for standard industrial use
  • SUS304 tube material for improved corrosion resistance
  • Galvanized surface treatment for rust protection
  • Chrome plated surface for wear resistance
  • PU or rubber coating for noise reduction and surface protection

Quality Control

  • Taper degree verified against the 3.6 specification
  • Shaft diameter checked for ø12 mm tolerance
  • Surface treatment confirmed per order requirement
  • Roller rotation tested for smooth movement
  • Housing material verified as nylong and PP

Customization Options

  • Choose between steel or SUS304 tube material
  • Select surface treatment: galvanized, chrome plated, PU or rubber coating
  • Order based on shaft diameter of ø12 mm and taper degree of 3.6
  • Specify required length and width as 11 mm each
  • Match the model number to the required load and application

Use Guide

  • Ensure the shaft diameter matches ø12 mm for proper fit
  • Verify the taper degree is 3.6 for correct alignment in the housing
  • Select surface treatment based on environmental conditions
  • Use the 11 mm length and width for space-limited installations
  • Confirm the roller is mounted with the small end diameter facing the load direction
