Description
Product Overview
The uxcell B-68 Needle Roller Bearings are engineered for demanding environments where strength, durability, and efficiency are paramount. Constructed from premium chrome steel, each bearing offers exceptional wear resistance and a long service life, even under continuous heavy loads. The full complement design eliminates the need for a cage, allowing a greater number of rollers to be packed within the same bearing volume. This results in a higher radial load capacity and improved stiffness, making the bearing suitable for applications that require compact yet powerful solutions. The dimensions—3/8 inch inner diameter, 9/16 inch outer diameter, and a total thickness of 1/2 inch with washers—provide a versatile fit for a wide range of machinery, from agricultural implements to industrial gearboxes. The precision manufacturing process ensures tight tolerances, smooth operation, and reduced friction, which translates into lower energy consumption and extended equipment lifespan.
Usage
These needle roller bearings excel in settings where high radial loads are encountered and space is limited. In the agricultural sector, they are commonly installed in combine harvesters, seed drills, and fertilizer spreaders, where they support shafts that experience constant vibration and heavy torque. In industrial applications, the B-68 model is a preferred choice for conveyor systems, motor shafts, and pump assemblies, delivering reliable performance in continuous operation environments. Automotive manufacturers also integrate these bearings into transmission components and steering systems, benefiting from the reduced friction and enhanced load-bearing capabilities. The bearing’s open‑end design simplifies installation and maintenance, allowing technicians to replace or service the bearing without disassembling the entire assembly. Whether the equipment operates in a factory floor, a farm field, or a vehicle chassis, the B-68 bearing provides consistent performance, minimizing downtime and maintenance costs.

FAQ
What does “full complement” mean for a needle roller bearing?
A full complement bearing does not include a cage, which allows a higher number of rollers to be packed into the bearing. This increases the radial load capacity and stiffness, making the bearing suitable for applications that demand high strength in a compact form factor.
Can these bearings be used in high‑temperature environments?
Yes. The chrome steel material used in the B‑68 model retains its mechanical properties at elevated temperatures, typically up to 200 °C (392 °F). However, for extreme temperature conditions, it is recommended to verify the specific operating limits with the equipment manufacturer.
How do I install the B‑68 bearing correctly?
Begin by cleaning the shaft and housing to remove any debris or contaminants. Apply a thin layer of compatible grease to the rollers and raceways. Gently press the bearing onto the shaft using a bearing press or a suitable tool, ensuring even force distribution to avoid damaging the rollers. Verify that the bearing sits flush without any axial play before completing the assembly.
What maintenance practices extend the life of these bearings?
Regular inspection for signs of wear, contamination, or misalignment is essential. Keep the bearing lubricated with the recommended grease or oil, and replace lubrication according to the equipment’s maintenance schedule. Avoid exposing the bearing to corrosive chemicals, and ensure that operating loads do not exceed the specified limits to prevent premature failure.
Do you offer custom sizes or specifications?
Yes, uxcell provides a range of needle roller bearings in various sizes and configurations. If you require a specific dimension or a customized solution, please contact our technical sales team, and we will work with you to develop a bearing that meets your exact requirements.
