Koofull NTA613+2TRA Thrust Needle Roller Bearings Set
The NTA613 needle roller thrust bearings come as a 4-bearings package with 8 washers. Bore diameter is 3/8″, outer diameter 13/16″, and thickness 5/64″. Rollers are made from high-temperature bearing chromium steel for heat resistance and durability under heavy axial loads. This set is best for projects needing multiple, compact thrust elements in one kit. Caution: these bearings support axial loads in a single direction only, so correct orientation is essential.
Who this is best for: cabinetry or small machinery where axial loads run consistently in one direction and you want a ready-to-assemble kit with washers for spacing.
RPS-IND AXK3552 Thrust Needle Roller Bearings
AXK3552 bearings are designed for heavy-duty axial support with corrosion-resistant galvanized rollers. The set includes two high-carbon steel washers to provide robust compressive strength. Suitable for electric drills, angle grinders, lawn mowers, washing machines, printers, and copiers, these bearings excel where harsh environments demand reliability and long service life. Best for industrial or workshop applications requiring durable axial elements with washers that resist corrosion.
Who this is best for: users needing enhanced durability in mixed-tool environments, especially where washers improve mounting integrity and axial load capacity.
uxcell AXK120155 Thrust Needle Bearings With Washers
AXK120155 targets large I.D. applications, offering a 120mm inner diameter and 155mm outer diameter with a 4mm width. The rollers are chromium steel, paired with a steel cage to ensure even spacing and reduced friction. This arrangement helps reduce vibration and noise in high-load, axial-only scenarios. Best for large-diameter axial setups where space and load are critical considerations. Caution: ensure compatibility with existing bore and housing tolerances to avoid misalignment.
Who this is best for: equipment or fixtures requiring a high-diameter thrust element with reliable load distribution.
uxcell AXK2035 Thrust Needle Bearings With Washers
AXK2035 features a bore of 20mm and an outer diameter of 35mm with a 2mm thickness (4mm with washers). Chrome steel rollers and a steel cage provide wear resistance and stable spacing. Like other needle thrust bearings, it accommodates axial loads in one direction. This option is best for compact assemblies where a medium bore size and light-to-moderate axial loads are present. Caution: verify that the overall assembly width matches your housing to avoid interference.
GUSIRUI 51101 Series Thrust Ball Bearing
This option moves away from needle roller thrusts toward a single-row axial ball bearing design, suitable for different load and speed profiles. Material is chrome steel, with the axial load-capable design appropriate for lower speed or lighter axial requirements. Choose this if your application benefits from ball bearing characteristics and straightforward mounting. Best for projects where a simple, robust axial bearing is adequate and precise alignment is achievable.
Buying Guide
How to choose the right cylindrical roller thrust bearing
Determine your axial load direction and magnitude. Needle roller thrust bearings are ideal for high-load, directional axial support, but only in one direction. If your application requires variable load directions, a ball-bearing option or a different configuration may be better.
Check bore and outer diameters carefully. Ensure the bearing ID matches the shaft and the OD fits the housing bore without excessive clearance. Consider spacers and washers included in some sets to simplify mounting and alignment.
Assess material and corrosion resistance. Chrome steel rollers offer wear resistance and heat tolerance, which matters in machines with frequent operation or high temperatures. Washers made of steel provide additional support but ensure compatibility with your housing design.
Consider total package and mounting hardware. Kits that include washers simplify assembly and alignment. If your design requires extra components, a complete set helps maintain axial load distribution and reduces setup time.
Evaluate speed and lubrication needs. Axial loads with low-speed operation often suit thrust needle or ball bearings, while higher speeds demand careful lubrication planning to prevent heat buildup and wear.
Installation tolerance and symmetry. Some bearings require precise tolerances to avoid misalignment. Ensure the housing and shafts are machined to the recommended tolerances for best results.
Practical questions to consider
- What is the expected axial load direction and duration?
- Do I need a large bore size to fit a specific shaft?
- Is corrosion resistance important for your environment?
- Do I prefer a kit with washers included for easier mounting?
- Will the assembly operate at high or low speeds?
- Is space or height a critical constraint in the housing?

FAQ
- What is a cylindrical roller thrust bearing?
Answer: It is a type of bearing designed to support axial loads using cylindrical rollers aligned parallel to the shaft, offering high load capacity in a compact form. - Do these bearings support loads in both directions?
Answer: Many needle roller thrust bearings support axial loads in a single direction only; verify the data sheet for your exact model. - Which materials are common for these bearings?
Answer: Chrome steel rollers and steel cages are typical for durability and heat tolerance. - Should washers be included?
Answer: Washers are often included or recommended to improve alignment and load distribution in the mounting housing. - What factors influence bearing life?
Answer: Load direction, load magnitude, speed, lubrication, housing fit, and operating temperature all affect life and performance. - Is a ball-bearing alternative better for certain apps?
Answer: If you need multidirectional speed with different load profiles, a thrust ball bearing may be more versatile, but it offers different load characteristics than needle roller thrust bearings.
