SKF 61916-2RZ 80x110x16 mm

SKF 61916-2RZ 80x110x16 mm - Single Row Deep Groove Ball Bearing

SKF 61916-2RZ is a single-row deep groove ball bearing with dimensions of 80x110x16 mm, manufactured by SKF. It belongs to the thin-section 619 dimensional series and features two RZ low-friction seals, one on each side. Its deep raceway grooves allow it to accommodate radial loads and axial loads in both directions, within the bearing's operating limits.

Technical Specifications - SKF 61916-2RZ

What Does SKF 61916-2RZ Mean?

The designation 61916-2RZ identifies the bearing's basic design, dimensional series, bore size and sealing arrangement.

61916 - Bearing series and bore code

• 6 - Single-row deep groove ball bearing.

• 19 - Thin-section dimensional series.

• 16 - Bore code corresponding to an 80 mm bore diameter.

2RZ - Low-friction seals on both sides

• RZ - SKF designation for a low-friction seal.

• 2RZ - Two low-friction seals, one fitted on each side of the bearing.

The RZ seals help retain lubricant and restrict the entry of contaminants while limiting frictional resistance.

The 2RZ execution should not be confused with SKF 2RS1, 2RSH or 2Z designs. These suffixes identify different sealing or shielding arrangements.

Bearing Construction and Operating Characteristics

Thin-Section 619 Series

SKF 61916-2RZ has an 80 mm bore, 110 mm outside diameter and 16 mm width.

The radial cross-section height is calculated as:

(110 - 80) / 2 = 15 mm.

This relatively small cross-section makes the 619 series relevant to mechanical designs with restricted radial installation space.

However, a smaller bearing cross-section also limits the space available for rolling elements. Bearing load ratings must therefore be checked rather than inferred from bore diameter alone.

Inner Ring, Outer Ring and Rolling Elements

The bearing contains an inner ring, an outer ring and one row of balls operating in deep raceway grooves.

This geometry primarily supports radial loads while also permitting axial loading in both directions.

The permissible combination of radial and axial loading depends on the bearing's technical ratings and operating conditions.

RZ Low-Friction Seals

The 2RZ execution incorporates low-friction seals on both sides of the bearing.

These seals provide a barrier against contamination and help retain the lubricant inside the bearing.

Their reduced-friction design is particularly relevant when limiting seal-generated friction and heat is important.

However, RZ seals should not be regarded as providing complete protection against water, aggressive fluids or severe contamination.

The suitability of the sealing arrangement must be evaluated against the actual operating environment.

Load Ratings and Speed Considerations

SKF bearing selection requires evaluation of the basic dynamic load rating C, basic static load rating C0, fatigue load limit Pu and permissible operating speed.

For SKF 61916-2RZ, these values must be taken from the manufacturer's data for the exact bearing execution. Values from open, shielded or differently sealed 61916 variants should not be transferred automatically.

The reference speed and limiting speed also have different meanings. A reference speed relates to thermal operating conditions, while the limiting speed reflects mechanical or other design constraints. Neither should be treated as an unconditional permissible operating speed.

Alternative Designations and Search References

The following are practical search and purchasing variations of the same bearing designation:

• SKF 61916-2RZ

• 61916-2RZ SKF

• 61916 2RZ SKF

• SKF61916-2RZ

The manufacturer's designation is 61916-2RZ.

The basic designation 61916 without the 2RZ suffix does not identify the same sealed execution.

SKF 61916-2RZ vs Other 61916 Variants

Bearings in the same dimensional series may share boundary dimensions while having different sealing arrangements and operating characteristics.

61916-2RZ vs 61916-2RS1

The principal difference is the sealing concept.

The 2RZ execution is designed to limit seal friction, while the 2RS1 execution uses contact seals that provide a different balance between sealing effectiveness and friction.

For applications exposed to contamination, sealing performance may be more important than minimizing frictional torque.

For applications where seal friction and heat generation are critical, a low-friction seal design may be advantageous.

These executions should not be substituted without checking the operating requirements.

61916-2RZ vs Open 61916

An open bearing does not incorporate the same integrated sealing arrangement.

Its use requires an appropriate lubrication and contamination-protection strategy within the machine.

An open 61916 bearing should not automatically replace a sealed 61916-2RZ bearing, even where the basic mounting dimensions are identical.

Bearing Selection and Interchangeability

Before ordering SKF 61916-2RZ, verify the complete manufacturer designation and the following requirements:

• Bore diameter: 80 mm.

• Outside diameter: 110 mm.

• Width: 16 mm.

• Low-friction sealing arrangement: 2RZ.

• Required radial and axial load capacity.

• Internal clearance required by the application.

• Shaft and housing fits.

• Operating speed.

• Operating temperature.

• Lubrication and contamination conditions.

The internal clearance should not be assumed solely from the absence of a clearance suffix. The actual requirement must be assessed against the bearing specification and mounting conditions.

A bearing from another manufacturer with dimensions of 80x110x16 mm is not necessarily a fully interchangeable replacement.

Differences in sealing design, internal clearance, load ratings, cage construction and speed capability may affect performance.

Applications of SKF 61916-2RZ

The thin-section geometry of the SKF 619 series is relevant to rotating mechanical assemblies where radial installation space is limited.

The 2RZ execution is suitable for consideration where a low-friction sealing arrangement is required to help retain lubricant and restrict contamination.

Potential application categories for this bearing design include compact shaft supports and industrial rotating assemblies, provided that the loads, speeds and environmental conditions are compatible with the selected bearing.

These are general applications of the bearing design, not verified OEM applications of the exact 61916-2RZ part number.

Suitability for a particular motor, pump, gearbox or other machine must be confirmed from its technical requirements.

Installation and Handling

Correct installation is essential to preserve the bearing's internal geometry and operating performance.

Clean mounting conditions

Keep the bearing sealed in its original packaging until installation. Prevent dirt, moisture and metal particles from entering the assembly.

Correct mounting force

When installing the inner ring with an interference fit, apply mounting force to the inner ring. When pressing the outer ring into a housing, apply force to the outer ring.

Do not transmit mounting forces through the balls and raceways.

Shaft and housing inspection

Check the mounting surfaces, dimensional tolerances, alignment and shoulder geometry before installation.

Seal protection

Avoid damaging or removing the RZ seals. Do not introduce additional grease or alter the factory lubrication without an appropriate technical reason.

Storage

Store the bearing in a clean, dry environment, preferably in its original packaging.
