How the 6013-2RS-NTN model number is decoded

6013-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 13 by five gives the 65 mm bore; the 100 mm outside diameter and 18 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 65 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. NTN's contact-seal catalogue number is 6013LLU (suffix LLU, or LLH low-torque variant), mapped here from the industry-neutral -2RS spelling; the contacting lip lowers the speed ceiling versus the open bearing.

Typical equipment & failure modes

Common applications

  • centrifugal and positive-displacement pumps
  • gearboxes and speed reducers
  • conveyor drives
  • material-handling equipment

Known failure patterns

  • seal-lip hardening and loss of pre-grease in sustained high-temperature service
  • grease-life expiry in the sealed-for-life cavity (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

  • Temperature rise and interference fits consume internal clearance on this 65 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6013 with C3 for those conditions.
  • The 60xx extra-light section at 65 mm bore uses a smaller 100 mm OD than a 6213; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
  • Contact seals add drag and heat: 6013-2RS-NTN runs slower and cooler-limited than the open 6013; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
  • Never wash a sealed 6013-2RS-NTN in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
  • Measure the shaft, do not trust the drawing: a 65 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6013-2RS-NTN.
  • Deep-groove ball bearings tolerate only minutes of misalignment; if the 100 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6013-2RS-NTN.
  • NTN catalogues the contact-sealed version as 6013LLU (suffix LLU), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing.
  • At 65 mm bore 6013 is in NTN's upper general-purpose range; the pressed-steel cage is standard but mid-section 63xx sizes at this bore can be ordered with a machined brass cage (suffix M) for heavy-shock or very-low-speed duty — confirm cage material with the NTN channel if the application sees impact loads.
  • NTN lists the grease limiting speed at 3900 r/min for 6013; this is a large or heavy-section size where centrifugal force and cage inertia cap the speed — for higher shaft speeds either step to a smaller bearing on the same bore or consult NTN for an oil-lubricated, machined-cage variant.
  • At 34 kN dynamic load rating (C) and 25.2 kN static (C0), 1.83 kN fatigue load limit Cu, 6013 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 421 g, 6013 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 65×100×18 mm envelope of 6013 gives a D/d ratio of 1.54 and 17.5 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 34/25.2 kN load ratings, 1.83 kN fatigue load limit Cu NTN lists the grease limiting speed at 3900 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 421 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6013LLU on the 65×100×18 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6013 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.
  • NTN's pressed-steel cage (no cage suffix) is the quiet standard for this size; for sustained running close to the limiting speed or for heavy shock duty, ask the NTN channel whether a machined-cage execution of 6013 is listed.

Frequently asked questions

What are the dimensions of a 6013-2RS-NTN bearing?

A 6013-2RS-NTN deep-groove ball bearing has a 65 mm bore, 100 mm outer diameter and 18 mm width (2.559 × 3.937 × 0.709 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.

What does the 2RS suffix on 6013-2RS mean?

2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.

How does the 6000 compare with other series at the same 65 mm bore?

The second digit is the diameter series: 60 is the smallest standard section (100×18 mm, 17.5 mm radial section) at 65 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.

What is the NTN suffix for a sealed 6013?

NTN uses suffix LLU for the contact rubber seal (catalogue number 6013LLU), 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 65×100×18 mm ISO 15 envelope.

Does NTN offer 6013 with C3 clearance?

Yes — most NTN deep-groove sizes can be ordered with C3 internal clearance (suffix C3 follows the seal code). C3 suits tight fits and hot shafts; for normal fits at moderate temperature the standard CN clearance of 6013LLU is the correct choice.
