Product No.: 330101-00-56-10-02-00 - General Introduction
This product is a precision, large-bore clamping shaft collar designed for robust axial positioning and light-duty power transmission on substantial shafts. It belongs to the same modular family of mechanical components as previously referenced parts. The bore size of 56mm indicates its application in medium to heavy-duty machinery. The collar utilizes a set screw clamping mechanism, providing a secure and adjustable hold, and is engineered for applications where high concentricity and reliability are required on larger diameter shafts.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Bore Size (I.D.) | 56 mm | The "-56-" segment specifies the precise inner diameter, designed for a nominal 56mm shaft (likely with h7 or h8 tolerance for fit). |
| Outer Diameter (O.D.) | Approx. 70 - 75 mm | The "-10-" likely refers to a standard series size, resulting in a proportional outer diameter that provides adequate wall thickness for strength and clamping force. |
| Width / Thickness | Approx. 15 - 20 mm | Substantial width to distribute clamping load, ensure stability, and provide a sufficient engagement surface. |
| Clamping Mechanism | Radial Set Screw(s) | The "-02-" variant typically specifies the use of one or two socket head set screws tightened perpendicular to the shaft axis to generate holding friction. |
| Set Screw Specification | Likely M6 or M8 socket head cap screws. | Sized appropriately for the collar's dimensions to generate sufficient clamping force without stripping threads. May feature a cup point or nylon tip to prevent shaft damage. |
| Primary Material | Carbon Steel (e.g., 1045) with Black Oxide Finish or Stainless Steel (304/316). | Carbon steel with black oxide is common for strength and cost-effectiveness. Stainless steel is used in corrosive environments. Aluminum is less common for this size due to lower strength. |
| Finish | Black Oxide (for steel) or Passivated (for stainless). | Black oxide provides corrosion resistance, reduces light reflection, and minimizes galling. |
| Weight | Approx. 200 - 400 grams | Significant weight due to the large size and dense material, contributing to its solid feel and vibration damping. |
| Key Feature | Large Bore Precision. | Machined to tight tolerances to ensure minimal runout (< 0.05 mm TIR typical) and uniform contact with the shaft, crucial for balanced operation at moderate speeds. |
| Installation | Requires a clean, smooth shaft surface within specified diameter tolerance. Set screws must be torqued to specification in a cross-tightening pattern if multiple screws are present. | Proper installation is key to achieving rated holding power and preventing shaft damage. |
| Holding Torque | High. Capable of transmitting significant torque through friction alone on a properly prepared shaft, suitable for acting as a simple gear or pulley hub. |
Primary Application Scenarios
This component is used in industrial machinery where large shafts require secure, adjustable axial location or simple torque transfer.
Industrial Gearbox & Reducer Shafts:
Bearing Spacing & Axial Location: Used to precisely position and secure bearings on intermediate or output shafts within gearboxes, providing a fixed reference point and taking up axial play.
Large Electric Motor & Generator Shafts:
Coupling Hub Positioning: Installed on motor shaft extensions to act as a positive stop for mounting flexible couplings or coupling guards, ensuring proper air gap and alignment.
Material Handling Conveyor Systems:
Pulley & Sprocket Retention: Serves as a locking collar to secure large conveyor drive pulleys, wing pulleys, or chain sprockets to their shafts, preventing axial creep under load.
Paper & Steel Mill Roller Assemblies:
Roll End Positioning: Used on the non-driven ends of various rollers (e.g., idler rollers, guide rollers) to axially locate them within the machine frame and prevent lateral movement.
Heavy-Duty Pump & Fan Shafts:
Impeller Spacing & Guard Mounting: Acts as a spacer between impellers and bearings in some pump designs, or as a mounting point for internal baffles or external protective covers on pumps and large industrial fans.
