INA NATR 6 PP A 6x19x12 - Industrial Yoke-Type Track Roller

Technical Specifications & Design

The INA NATR 6 PP A 6x19x12 track roller is a precision-engineered yoke-type rolling bearing unit designed for demanding industrial use. With inner diameter d = 6 mm, outer diameter D = 19 mm and width B = 12 mm, it offers compact dimensions while delivering significant performance. The “PP” suffix denotes double-side plastic plain washers with NBR sealing lips, providing a three-stage sealing system. The “A” modification indicates enhanced internal construction for improved durability and load performance. This unit features a thick-walled outer ring with optimized profile and needle-roller assembly, enabling high radial load capacity and the ability to absorb axial loads due to slight misalignment. Typical dynamic load rating around 3 550 N and static rating around 4 100 N, grease limited speed approx. 11 000 rpm. Its structural design makes it an outstanding choice for small-format yet high-load bearing applications.

Applications in Industrial Use

This bearing unit is tailored for industrial applications where space is limited but high durability is required. Typical uses include conveyor systems, linear guides, machine frames, cam mechanism follow-rollers, heavy-duty automation components and bearing housing assemblies. Thanks to its compact size (6x19x12 mm) and robust design, it fits seamlessly into machine constructions requiring a bearing unit or obudowa łożyskowa with high load capacity and low maintenance. Its sealed design suits operations with dust, dirt or occasional moisture exposure, offering high reliability across transport, packaging, automation and mechanical engineering sectors.

Benefits for B2B Buyers

For industrial customers, this track roller brings measurable advantages:

• High durability: Optimised needle-roller assembly and thick outer ring extend lifespan and withstand heavy load cycles.

• Low maintenance: Double-side PP sealing limits contaminant ingress and preserves lubrication, reducing downtime.

• Compact yet strong: The compact size (6 mm bore) allows integration into smaller assemblies while delivering robust performance.

• Versatile installation: Suitable for yoke-type mounting on shafts or within machine frames, offering flexibility.

• Fast supply: With stock status and ready dispatch, you benefit from quick fulfilment in B2B supply chains.

FAQ

Q: What makes this track roller different from standard ball bearings?
A: Unlike typical łożysko kulkowe, this unit uses a yoke-type design with needle rollers and thick outer ring, providing higher radial load capacity and tolerating slight axial loads and misalignment.

Q: Can the INA NATR 6 PP A handle dusty or moderate moisture environments?
A: Yes. The PP version features three-stage sealing—plastic plain washers and NBR lips—effectively protecting the needle-roller assembly and reducing contamination, making it suitable for industrial transport or automation use.

Q: What installation options exist for this roller unit?
A: This bearing unit supports shaft or stud mounting in yoke applications, enabling it to serve as a durable element within a bearing housing (obudowa łożyskowa) or integrated machine frame.

Q: What are the typical load and speed ratings?
A: Approximate dynamic radial load rating is 3 550 N, static radial about 4 100 N, and grease-lubricated speed up to about 11 000 rpm—subject to application conditions and lubrication.

Q: Is the unit readily available for B2B ordering with fast delivery?
A: Yes — our warehouse is stocked for bulk industrial orders and dispatch is possible within 24 h to meet production or maintenance schedules.
