uxcell Flanged Sleeve Bearing, POM (ID 14mm x OD 16mm x 12mm)
The 6-pack of POM bushings provides reliable self-lubricating performance with a bore of 14 mm, outer diameter of 16 mm, and length of 12 mm. The flange measures 22 mm in diameter and 1 mm thick, helping to lock the bearing in place and prevent axial movement. POM materials offer low friction, good load-bearing capacity, and wear resistance, translating to durable operation in light to moderate loads. These bushings support shafts and fasteners while maintaining alignment and reducing wear in compact assemblies.
Key points include:
– Material and maintenance: POM is inherently self-lubricating and maintenance-free.
– Structural support: The flange stabilizes the bearing and prevents shifting during installation.
– Application fit: Ideal for small, precise mechanisms where shaft guidance and reduced friction are needed.
uxcell Nylon Flanged Sleeve Bearing, 8mm Bore
This 24-piece nylon-based flange bearing set features an 8 mm bore, 10.6 mm outer diameter, and 12 mm length, with a 16 mm flange diameter and 1.5 mm flange thickness. Nylon bushings are self-lubricating, offering strong load capacity and wear resistance suitable for repeated motion with reduced maintenance. They are well-suited for linear guides, door mechanisms, printer components, and other small-scale machines where quiet, smooth motion is desirable. The metal-to-plastic interface typically benefits from lower noise and less vibration.
Highlights include:
– Durable nylon composition for long life in continuous operation.
– Flange provides precise positioning and resistance to axial displacement.
– Lightweight alternative to metal bushings for low-load applications.
uxcell Flanged Sleeve Bearing, POM, ID 6mm
With a bore of 6 mm and an outer diameter of 7 mm, this 8 mm long POM bushing includes a small flange (11 mm diameter) and a 0.5 mm flange thickness. The package typically includes six pieces, offering flexibility in designs requiring multiple bushings in a single assembly. The POM material maintains low friction, tolerates wear well, and supports stable shaft guidance while curbing wear on mating components.
Considerations for use:
– Ideal for compact mechanisms where space is at a premium.
– Flange diameter and thickness accommodate straightforward alignment and stopping of axial movement.
– Self-lubricating nature minimizes maintenance in remote or hard-to-service environments.
HARFINGTON 8pcs POM Flanged Sleeve Bearings
HARFINGTON offers an 8-piece set of POM bushings with a bore of 3 mm, outer diameter of 4.6 mm, and length of 5 mm. The flange diameter is 4.6 mm with a thin flange profile, designed for even smaller assemblies where micro-movement and precise alignment matter. POM’s low friction and chemical resistance ensure reliable service across light mechanical chores, including small actuators and micro-robotics components.
Key strengths:
– Very compact footprint suitable for miniature devices.
– POM provides low friction and good wear resistance for continuous cycles.
– Chemical resistance makes it compatible with oils and solvents encountered in small machinery.
uxcell Nylon Flanged Sleeve Bearings, 5mm Bore
This set includes 24 nylon bushings with a 5 mm bore, 7.2 mm outer diameter, and 13.5 mm length. The flange diameter is 10 mm with a 1.5 mm flange thickness. Nylon bushings provide excellent load capacity, wear resistance, and low maintenance. They are commonly used in linear guides, small machinery, and devices requiring quiet operation and reduced friction. The larger quantity supports multi-location installations or projects that require more than one bushing in a single build.
Considerations:
– Nylon’s self-lubricating properties reduce upkeep in environments where lubrication is difficult.
– The 10 mm flange diameter helps ensure reliable seating and axial restraint.
– Suitable for moderate-load applications and repetitive motion.
uxcell Flanged Sleeve Bearings, Nylon, 8mm Bore
This set features 12 nylon bushings with an 8 mm bore, 10 mm outer diameter, and 12.5 mm length. The flange diameter is 14 mm with a 2.5 mm flange thickness. Nylon’s strong load-bearing capabilities and low friction properties make these bushings a popular choice for guiding shafts in compact applications. They help reduce vibration and noise, supporting smoother operation in devices like small printers, CNC components, and robotics joints.
Practical notes:
– Nylon’s wear resistance extends service life under frequent movement.
– The larger flange aids in precise positioning and axial stabilization.
– A flexible option for projects requiring multiple bushings with consistent performance.
Buying Guide: Key Purchase Considerations for Small Plastic Flange Bushings
- Material selection: POM (polyoxymethylene) offers very low friction and high wear resistance, ideal for precise, low-maintenance use. Nylon provides good load capacity and strength with moisture tolerance, suitable for general-purpose applications.
- Bore, outer diameter, and length: Match bore size to your shaft diameter, ensure outer dimensions fit bearing housings, and check flange diameter and thickness to secure axial positioning.
- Flange design: A correctly sized flange prevents axial movement and assists with alignment during installation. Consider flange thickness for clearance in tight spaces.
- Load and wear considerations: For high-load or high-cycle environments, assess material stability and compatibility with lubricants or oils in use. POM generally handles wear well in light to moderate loads; nylon handles moderate loads with added resilience to moisture.
- Maintenance needs: Self-lubricating plastics minimize periodic lubrication, but design should still accommodate occasional re-lubrication or inspection in dusty or dirty environments.
- Environmental compatibility: Chemical resistance is valuable when parts contact fuels, solvents, or cleaners. POM and nylon provide varying degrees of chemical tolerance; verify compatibility with your application fluids.
- Assembly considerations: Ensure you can access and secure the flange; verify that the mounting surface is flat and free of debris to avoid uneven seating or binding.
- Quantity and flexibility: Sets with multiple bushings reduce procurement hassle for multi-location projects or future expansions. Consider whether you’ll need identical bushings or a mix for different axes.
Overall, these small plastic flange bushings deliver a practical balance of low friction, reliable wear resistance, and straightforward installation. When choosing, prioritize bore compatibility, flange dimensions, and material behavior under your expected load and environmental conditions. By aligning these factors with your project needs, you can optimize shaft guidance, reduce noise, and extend the life of compact mechanical assemblies.
