How the 6034-2RS model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6034 carries bore code 34 = 170 mm. Outside diameter 260 mm and width 42 mm come from the ISO 15 boundary-dimensions general plan. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. For normal-load mounting with a rotating inner ring on a 170 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. FAG's catalogue order number is 6034-2RSR (suffix -2RSR), mapped here from the industry-neutral -2RS spelling.
Typical equipment & failure modes
Common applications
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
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)
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
Selection pitfalls — read before you substitute
- Mount this 170 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 60xx extra-light section at 170 mm bore uses a smaller 260 mm OD than a 6234; 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: 6034-2RS runs slower and cooler-limited than the open 6034; 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 6034-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 260 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6034-2RS.
- FAG catalogues the contact-sealed version as 6034-2RSR (suffix -2RSR, or -2HRS on Generation-C sizes), 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.
Frequently asked questions
What are the dimensions of a 6034-2RS bearing?
A 6034-2RS deep-groove ball bearing has a 170 mm bore, 260 mm outer diameter and 42 mm width (6.693 × 10.236 × 1.654 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
How does the 6034 bore code work?
The last two digits of 6034 are bore code 34, giving 34 × 5 = 170 mm bore. The 260 mm outside diameter and 42 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 6034-2RS 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 170 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (260×42 mm, 45.0 mm radial section) at 170 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the FAG designation and catalogue data for 6034-2RS?
In the Schaeffler FAG Rolling Bearings catalogue (HR 1, Jan 2020) this size is listed as 6034-2RSR — two contacting rubber seals over a lifetime grease fill (FAG suffix -2RSR/-2HRS), 170×260×42 mm per ISO 15. Quoted values: C 179 kN, C0 172 kN, mass 7120 g. Limiting speed 1340 rpm. The industry-neutral page spelling 6034-2RS follows the seal-suffix convention used across this site, not FAG order-number spelling.
