Product Description

Low-Friction, High-Speed Tapered Roller Bearings 31305/Df 31309/Cl7cdfg40 33014/Df 33115/Dfc150
Product Description
    Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation.
    The inner ring, with rollers and cage, can be mounted separately from the outer ring.
    These separable and interchangeable components facilitate mounting, dismounting and maintenance.
    By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.
Low-Friction, High-Speed Tapered Roller Bearings 31305/Df 31309/Cl7cdfg40 33014/Df 33115/Dfc150

    The design advantages of tapered roller bearings are as follows. Firstly, they can handle both radial and axial loads, providing a more comprehensive load-bearing capacity. Secondly, the tapered rollers in the bearing allow for better distribution of the load, reducing stress on individual components and increasing the bearing's durability.
    Additionally, the design of tapered roller bearings enables them to operate at higher speeds with reduced friction and heat generation, improving the overall efficiency of the system. Finally, their compact design makes them suitable for a wide range of applications, especially in situations where space is limited.

Installation Instructions

Installation Guide for Tapered Roller Bearings


1. Pre-Installation Preparation

  • Cleaning:
    Thoroughly clean the shaft, housing, and mating surfaces using lint-free cloths to remove contaminants such as dust, oil, or burrs.

  • Inspection:
    Verify the dimensional tolerances of the shaft and housing to ensure compatibility with the bearing's inner and outer rings (interference fit recommended for the inner ring, transition fit for the outer ring).

  • Tool Preparation:
    Prepare necessary tools, including hydraulic nuts, induction heaters (heating temperature ≤120°C), torque wrenches, and dial indicators for clearance measurement.

2. Installation Methods

  • Press-Fit Method:

    1. Align the inner ring (cone) with the shaft shoulder, ensuring no tilting occurs.

    2. Apply uniform pressure on the inner ring using a press or hydraulic tool. Avoid applying force directly to the outer ring (cup) or rollers.

    3. After installation, check for smooth rotation and ensure there is no abnormal noise or binding.

  • Thermal Mounting:

    1. Heat the inner ring to 80-120°C using an induction heater or oil bath (open flame heating is strictly prohibited).

    2. Quickly mount the heated inner ring onto the shaft and allow it to cool naturally.

  • Tapered Shaft Mounting:

    1. For tapered shafts, use a lock nut (e.g., KM-type nut) to axially press the inner ring against the shaft shoulder.

    2. Tighten the lock nut to the manufacturer-specified torque value and secure it with a locking device (e.g., tab washer).

3. Clearance Adjustment

  • Tapered roller bearings require proper axial clearance or preload adjustment to ensure optimal performance.

  • Measure the axial clearance using a dial indicator. Adjust the lock nut to achieve the recommended clearance (typically 0.02-0.05mm for standard applications).

  • For preloaded applications, follow the manufacturer's specifications to achieve the desired preload value.

4. Lubrication

  • Apply a high-quality lubricant (grease or oil) suitable for the operating conditions.

  • Fill 30-50% of the bearing's free space with grease for standard applications. For high-speed or high-temperature conditions, consider oil lubrication or oil-mist systems.

  • Ensure the lubricant is compatible with the bearing material and operating environment.

5. Sealing and Protection

  • Inspect and install appropriate seals (contact or non-contact type) to prevent contamination.

  • Ensure the sealing lip is oriented toward the contamination source.

  • Perform a no-load test run after installation to verify proper operation. Monitor temperature rise (ΔT ≤40°C) and vibration levels (≤ISO 10816 standards).

6. Prohibited Actions

  • Never strike the bearing rings or rollers directly with a hammer or other tools.

  • Avoid overheating the bearing during thermal mounting (maximum temperature: 120°C).

  • Do not mix incompatible lubricants or use contaminated grease.
