How the 6010-ZZ-NTN model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6010 carries bore code 10 = 50 mm. Outside diameter 80 mm and width 16 mm come from the ISO 15 boundary-dimensions general plan. Suffix -ZZ denotes two non-contact metallic shields; they retain grease and block coarse debris but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 50 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. NTN catalogue order number: 6010ZZ (suffix ZZ), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.
Typical equipment & failure modes
Common applications
- industrial electric motors
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
- conveyor drives
Known failure patterns
- fine-particle abrasion when non-contact shields let dust past in dirty duty
- grease aging in the shield-for-life cavity with no relubrication path
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Interference on a 50 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6010 with C3 clearance and re-check the residual value after mounting.
- The 60xx extra-light section at 50 mm bore uses a smaller 80 mm OD than a 6210; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- Do not wash 6010-ZZ-NTN in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
- Shielded 6010-ZZ-NTN units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
- Vibration during standstill brinells the raceways of a 50 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- Measure the shaft, do not trust the drawing: a 50 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6010-ZZ-NTN.
- NTN catalogues the shielded version as 6010ZZ — suffix ZZ, two non-contact steel shields. The industry-neutral page spelling is -ZZ; quote the NTN order number when buying through an NTN channel.
- The 50 mm bore puts 6010 in NTN's general-purpose industrial range; the standard pressed-steel cage and CN clearance cover most electric-motor and pump duty, but for continuous high-speed use specify the LLH low-torque seal (not LLU) and confirm the housing allows the listed limiting speed.
- At 6000 r/min the grease limiting speed for 6010 covers medium-duty industrial drives; the open or shielded execution can run continuously at this speed with standard lithium-soap grease.
- At 24.2 kN dynamic load rating (C) and 16.6 kN static (C0), 1.24 kN fatigue load limit Cu, 6010 is a medium-load bearing suitable for most electric-motor and pump duty; the C0/C0r ratio matters for preloaded or thrust-loaded arrangements, so confirm the static safety factor with the NTN catalogue.
- At 261 g, 6010 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
- The 50×80×16 mm envelope of 6010 gives a D/d ratio of 1.60 and 15.0 mm radial section height — this thin section saves space but is sensitive to misalignment and shock; confirm the housing stays round within IT7 and the shaft does not deflect past the raceway contact angle under load.
- The 24.2/16.6 kN load ratings, 1.24 kN fatigue load limit Cu NTN lists the grease limiting speed at 6000 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 261 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6010ZZ on the 50×80×16 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6010 in a rated drive.
- Factory-fill grease in NTN sealed units is a general-duty lithium-soap grease; food-grade, low-temperature and high-temperature fills are request options at order time, because LLU/LLB units are not meant to be opened and re-greased in the field.
- Standard catalogue stock of 6010 is the general-purpose execution; for low-noise motor duty NTN offers low-torque seal and special-grease variants in this size class, which are separate order numbers.
Frequently asked questions
What are the dimensions of a 6010-ZZ-NTN bearing?
A 6010-ZZ-NTN deep-groove ball bearing has a 50 mm bore, 80 mm outer diameter and 16 mm width (1.969 × 3.15 × 0.63 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
What does the ZZ suffix on 6010-ZZ mean?
ZZ means two non-contact sheet-metal shields, one each side. They retain factory grease and block coarse particles with little friction, but do not seal against liquids, fine dust or pressure washing.
How does the 6000 compare with other series at the same 50 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (80×16 mm, 15.0 mm radial section) at 50 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the NTN suffix for a sealed 6010?
NTN uses suffix LLU for the contact rubber seal (catalogue number 6010ZZ), LLB/LLF for non-contact rubber seals, LLH for the low-torque contact seal and ZZ for steel shields. The industry-neutral spellings on this page (-2RS / -RSR / -ZZ) map to those NTN suffixes while keeping the 50×80×16 mm ISO 15 envelope.
What cage does NTN fit in 6010ZZ?
Standard is a pressed-steel cage with no suffix; larger sizes or shock-loaded duty can be supplied with a machined brass cage (suffix M) as a separate order number. The catalogue figures quoted here are for the pressed-steel execution.
