Product Description 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. 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.Detailed Photos Product Parameters DesignationPrincipal dimensionsBasic load ratingsDesign variant/feature dynamicstatic d[mm]D[mm]B[mm]T[mm]C[kN]C0[kN] 331149 E/C675 384.175 546.1 400.05 400.05 8 000 16 600 TQON/GW BT4-8025 G/HA1C300VA903 384.175 546.1 400.05 400.05 6 160 15 000 TQOSN/GW BT4B 334042 E1/C575 385.762 514.35 317.5 317.5 3 910 10 000 TQOSN/GWSI BT4B 332824 E/C475 395 545 268 288.9 4 800 9 500 TQON/GW BT4B 331347 AG/HA1 406.4 565.15 381 381 6 050 15 600 TQO/GWI BT4B 331333 E/C575 409.575 546.1 334.962 334.962 5 700 13 200 TQON/GW BT4B 331226/HA1 431.8 571.5 336.55 336.55 4 950 14 000 TQO/GWI BT4B 334019 G/HA1 431.8 635 440 355.6 6 600 15 000 TQOE/GWI 332313 440 650 353.5 353.5 6 600 15 000 TQO/GWI BT4-8124 E/C550 440 580 360 360 6 200 14 300 TQON/GW BT4B 328944 G/HA1VA901 440 650 353.5 353.5 6 710 13 200 TQOS/GWISI BT4B 332773 E/C725 450 595 368 368 6 800 16 300 TQON/GW 331169 E/C500 457.2 596.9 276.226 279.4 4 570 10 800 TQON/GW BT4-8111 E2/C725 460 610 360 360 6 800 14 300 TQOSN/GWISI BT4B 331977 E/C725 460 610 360 360 7 500 16 300 TQO/GWI BT4B 328913 BG/HA1C555 475 600 368 368 5 720 16 600 TQON/GW BT4B 331259 BG/HA1C325 482.6 647.7 417.512 417.512 7 650 20 000 TQON/GW 331090 E/C700 489.026 634.873 320.675 320.675 6 300 14 600 TQON/GW BT4B 334014 BG/HA1VA901 489.026 634.873 320.675 320.675 4 840 12 500 TQOS/GWISI BT4-8135 E/C750 490 625 385 385 7 100 16 300 TQON/GW 331978 BG 540 690 400 400 7 480 21 200 TQON/GW 331165 A 558.8 736.6 322.262 322.262 6 270 16 600 TQO/WI BT4B 330993 AG/HA1 558.8 736.6 409.575 409.575 8 580 23 200 TQON/GW BT4-8153 E/C775 560 700 405 405 8 000 21 200 TQON/GW BT4B 328509/HA4 560 920 618 618 16 500 34 000 TQO.1/WI 331148 A 584.2 762 396.875 401.638 7 650 22 400 TQO/GWI BT4B 331189 E/C600 584.2 730.25 342.9 349.25 5 940 17 000 TQO/GWI BT4B 331093 BG/HA1 585.788 771.525 479.425 479.425 10 600 30 000 TQON/GW BT4B 331300 E/C775 595.312 844.55 615.95 615.95 16 600 36 500 TQON/GW BT4B 331625 E/C800 603.25 857.25 622.3 622.3 18 300 40 500 TQON/GWCertificationsPackaging & ShippingInstallation InstructionsInstallation Guide for Tapered Roller Bearings1. Pre-Installation PreparationCleaning: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 MethodsPress-Fit Method:Align the inner ring (cone) with the shaft shoulder, ensuring no tilting occurs.Apply uniform pressure on the inner ring using a press or hydraulic tool. Avoid applying force directly to the outer ring (cup) or rollers.After installation, check for smooth rotation and ensure there is no abnormal noise or binding.Thermal Mounting:Heat the inner ring to 80-120°C using an induction heater or oil bath (open flame heating is strictly prohibited).Quickly mount the heated inner ring onto the shaft and allow it to cool naturally.Tapered Shaft Mounting:For tapered shafts, use a lock nut (e.g., KM-type nut) to axially press the inner ring against the shaft shoulder.Tighten the lock nut to the manufacturer-specified torque value and secure it with a locking device (e.g., tab washer).3. Clearance AdjustmentTapered 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. LubricationApply 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 ProtectionInspect 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 ActionsNever 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.Company ProfileFAQQ1: What about the MOQ?
