INA: Schaeffler Expertise in Bearings and Linear Guidance

Since 1946, INA, a brand of the Schaeffler Group, has established itself as a global reference in bearings, linear guidance, and motion transmission solutions. The brand is renowned for the precision, durability, and technological innovation of its products — serving industrial engineering and mechanical performance.
A historic manufacturer of the needle cage and a specialist in compact, high-performance bearings, INA offers a complete range covering the needs of the automotive, machine tool, food processing, medical, and rail industries.

INA – Schaeffler Group Expertise

Founded in Germany, INA is one of the three leading brands of the family-owned Schaeffler Group, alongside FAG (precision and large-size bearings) and LuK (transmission systems). With unique German know-how, the brand designs bearings and linear guides that combine reliability, performance, and innovation.

A Wide Range of INA Bearings and Linear Guidance Systems

INA develops bearings and guidance systems to meet every industrial need:

• Ball bearings, single or double row, ensure smooth, stable rotation with low friction and support high speeds. Ideal for motors, fans, and pumps.
• Roller bearings use cylindrical, spherical, or tapered rolling elements instead of balls, offering a larger contact surface. They are used in gearboxes, heavy machinery, or shock-loaded applications where stability and longevity outweigh speed.
• Needle roller bearings, a historical specialty of the brand, use fine cylindrical rollers called needles as rolling elements. This design provides a very high radial load capacity within a compact diameter and width. Perfect for automotive applications, precision tools, and industrial equipment.
• Cam followers are compact roller or needle bearings integrated into a thick outer ring acting as a raceway. With or without a stud, they guide linear movement or follow a cam profile while withstanding heavy radial loads and repeated shocks. Designed for conveyors, automation machinery, and handling systems.
• Self-aligning bearings automatically compensate for misalignment between the shaft and housing thanks to their spherical geometry. This feature reduces internal stress and ensures smooth operation even under shaft deflection.

Linear Guidance

Complementing its bearing range, INA designs linear guidance systems for automation and handling applications. Ball bushings, guide rails, recirculating ball carriages, and roller carriages guarantee precise, quiet, and low-friction linear motion — even under heavy loads or at high speed.

Sealing and Protection Solutions

INA offers a complete range of sealing options to ensure bearing durability. Sealed versions (2Z, 2RS) provide effective protection against dust and moisture, while labyrinth seals, protective rings, and integrated micro-lubrication systems ensure reliable operation.

Choosing an INA Bearing: Key Technical Criteria

Selecting the right bearing depends on several factors:
• Type of load (radial, axial, or combined)
• Rotational speed
• Precision and tolerance requirements
• Operating temperature
• Sealing, lubrication, and environmental conditions (dust, humidity, chemicals, etc.)
• Mounting and maintenance requirements

Good to know: INA products comply with ISO 15, ISO 281, and ISO 492 standards, guaranteeing precise dimensional tolerances, load capacity calculated using standardised models, and interchangeability with other manufacturers.

INA Mounting Accessories and Components

INA also offers a range of accessories for assembly, maintenance, and servicing. Complementary components such as locking washers, sealing caps, bearing spacers, needle rollers, and locknuts ensure reliable installation and effective bearing protection.

Solutions for Every Industrial Sector

The INA brand provides bearings and guides suitable for a wide variety of industries:
• Automotive: gearbox bearings, timing rollers, tensioners
• Machine tools: precision ball spindles, guide rails
• Food processing: stainless steel bearings, NSF H1 lubricants, sealed housings
• Rail: axle bearings, integrated vibration monitoring
• Medical: miniature low-noise bearings, non-magnetic ceramics

INA and FAG: Two Complementary Brands, One Quality Standard

The Schaeffler Group combines the expertise of its INA and FAG brands to deliver complete bearing solutions. INA stands out for its needle bearings, linear guidance systems, and compact solutions, while FAG is recognised for its high-precision ball and roller bearings.
Both share the same production sites, manufacturing standards, and quality control processes. Whichever brand you choose, Schaeffler products guarantee the same level of excellence, reliability, and performance.
