High Load Taper Roller Bearing 25*52*16.25 - China Suppliers & Factory for Automotive, Mining, Wind Power Equipment

Structural Features of Tapered Roller Bearings

This product features conical inner and outer raceways paired with tapered rollers, designed such that all projection lines of the conical surfaces converge at a common point along the bearing axis. This unique structural design enhances load distribution, making it an ideal choice for various applications.

As a separable bearing, the inner ring, roller, and cage assembly can be easily removed from the outer ring, facilitating convenient installation, disassembly, and maintenance. Sourced from leading China suppliers and manufactured in specialized factories, these tapered roller bearings ensure high reliability and performance. Explore our range of products to find the perfect bearing solution for your needs.

    Industrial machinery

    Widely used in various industrial equipment that need to withstand radial and axial combined loads, such as gearboxes, motors, reducers, etc.

    Automobile field

    Commonly used in automobile wheel hub bearings, differential bearings and other parts, and can withstand complex loads generated during vehicle driving.

    Agricultural machinery

    30205 bearings are also used in the transmission system and wheel axle parts of tractors, harvesters, etc. to adapt to the harsh working conditions and large loads in agricultural operations.

    Other fields

    It can also be used in related equipment in mining machinery, engineering machinery, textile machinery and other industries.

    Installation precautions
    Clearance adjustment

    When installing single-row tapered roller bearings, the clearance needs to be adjusted by yourself to ensure the normal operation and service life of the bearings; double-row and four-row tapered roller bearings have preset clearances when leaving the factory, and usually no additional adjustment is required.

    Installation method

    When installing, the matching accuracy of the bearing, shaft and bearing seat should be ensured to avoid being too loose or too tight. At the same time, pay attention to the installation direction to ensure that the force direction of the tapered roller is correct.

    Lubrication and sealing

    Choosing the right lubricant and sealing method is crucial to the performance and life of the 30205 bearing. Depending on the use environment and working conditions, grease lubrication or oil lubrication can be selected, and corresponding sealing devices should be used to prevent lubricant leakage and external impurities from entering the bearing.

    Product description

    1. Taper Roller Bearing Introduction:

    Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance.

    2. Taper Roller Bearing Application:

    Tapered roller bearings are usually of a separate type, that is, a conical inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the outer bevel (outer ring). Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.

    3. Tapered Roller Bearing Suffix definition:

    A: Internal structure change
    B: Increased contact angle
    X: The external dimensions are in accordance with international standards.
    CD: Double outer ring with oil hole or oil groove.
    TD: Double inner ring with tapered bore.

    Frequently Asked Questions
    1. What are the key dimensions and basic load ratings of the 30205 tapered roller bearing?
    The 30205 metric bearing has a specification of 25*52*16.25 mm (Inner Ring Width: 15 mm, Outer Ring Width: 13 mm). It features a basic rated dynamic load of 38.1 kN and a basic rated static load of 33.5 kN.
    2. What industries and machinery commonly use 30205 bearings?
    30205 bearings are widely utilized across industrial machinery (gearboxes, reducers, electric motors), automotive components (wheel hubs, differentials), agricultural equipment (tractors, harvesters), as well as mining, metallurgy, and textile machinery.
    3. Is clearance adjustment required during the installation of 30205 bearings?
    Yes. When installing single-row tapered roller bearings like the 30205, the internal clearance must be manually adjusted during mounting to ensure optimal performance and service life. Double-row and four-row bearings typically feature preset factory clearances.
    4. What lubrication and sealing methods are recommended?
    Depending on operating speeds and environmental conditions, either grease lubrication (limiting speed up to 7300-11000 r/min) or oil lubrication (up to 9800-13000 r/min) can be used. Compatible seals (such as 2RS or external sealing devices) are essential to prevent lubricant leakage and ingress of contaminants.
    5. What do tapered roller bearing suffix codes like A, B, and X indicate?
    Suffix definitions indicate specific design variations: "A" denotes an internal structural change, "B" indicates an increased contact angle, "X" signifies boundary dimensions conforming to international standards, "CD" refers to a double outer ring with oil features, and "TD" indicates a double inner ring with a tapered bore.
    6. What warranty and customization options are offered?
    Bearings are backed by a 12-month warranty from the date of shipment against manufacturing and material defects. In addition, full OEM customization, specialized packaging, laser marking, and tailored logistical solutions are available.
