Nachi Bearing 6005 6007 2NSE Single Row Double Sealed Deep Groove Ball Bearing

Need a replacement deep groove ball bearing for a woodworking machine spindle or feed roller? The 6007-2NSE and 6005-2NSE are single-row, double-sealed ball bearings that fit the existing housing without modification. 6007-2NSE: 35 mm bore, 62 mm OD, 14 mm width. 6005-2NSE: 25 mm bore, 47 mm OD, 12 mm width. Both carry a rubber seal on each face, so wood dust stays out and grease stays in. Carbon steel rings, ball bearing type, NSE seal specification, listed as a woodworking machine spare.

A woodworking line that stops for a seized bearing loses the same three things every time: an hour of production while the spindle is stripped down, a replacement ordered by guesswork from a number copied off a worn part, and a second failure a few weeks later because an open bearing swallowed fine MDF dust. The 6007-2NSE and 6005-2NSE are built to remove all three.

Both are single-row deep-groove ball bearings. One row of balls runs in deep, continuous grooves ground into the inner and outer rings, so a single unit carries radial load and axial load in either direction without a second bearing. The 2NSE suffix is the seal code: a rubber seal on each face. On a woodworking machine that matters, because dust and chips fine enough to pass an open bearing's clearance reach the ball track in days, not months.

Sizes are standard. 6007-2NSE measures 35 mm bore × 62 mm OD × 14 mm width; 6005-2NSE measures 25 mm bore × 47 mm OD × 12 mm width. Both rings are carbon steel, both are ball type, and both are listed under woodworking machine spares.

Why it matters: a bearing number you can read off the old part and check with a caliper before ordering is a bearing you fit once and forget until the next scheduled service.

What separates these two numbers from a generic sealed bearing:

• Two bores, one listing — 6007-2NSE is 35 × 62 × 14 mm, 6005-2NSE is 25 × 47 × 12 mm: spindle and feed roller from one order.
• Deep groove raceway — the track is ground deep into both rings, so one bearing takes radial and axial load in two directions.
• Sealed on both faces — a rubber seal sits front and back, holding grease in and keeping wood dust and moisture out of the ball track.
• Single row, narrow section — one ball row keeps the section 12 mm or 14 mm wide — the envelope the shaft was designed around.
• Carbon steel rings — ring and ball material is carbon steel, the grade stated on this listing, not an alloy substitute.
• Standard designation — 6005-2NSE and 6007-2NSE are standard bearing numbers, readable against the worn part before anything is removed.
• NSE seal specification — the seal spec is listed as NSE, so the seal style is fixed at the order stage, not discovered on delivery.
• Radial and axial in one — side load from a feed roller and radial load from the shaft ride on the same one ball row.
• Woodworking duty — listed application is woodworking machine spare — the dust-heavy duty these seals are specified for.

A workshop with a bearing down has two choices: wait for an outside supplier, or fit whatever is on the shelf and hope. These two numbers remove that choice.

• Fit it once, correctly. Because bore, OD and width are standard (35/62/14 and 25/47/12), the part that arrives matches the part that came out.
• Dust stops at the seal. two rubber seals mean the ball track sees clean grease instead of MDF dust, so the replacement interval is counted in service hours, not weeks.
• One order, two positions. a machine usually needs both numbers; stocking 6005-2NSE and 6007-2NSE together covers spindle and roller from a single purchase order.
• No machining, no shims. nothing is adapted to make it fit: the bearing drops into the existing housing at 12 mm or 14 mm width.
• Both load directions covered. the deep groove takes radial and axial load, so the assembly needs no extra thrust washer or second bearing.
• Readable number, repeatable order. the designation on the part is the same text used here, so the next reorder needs no caliper work.
• Predictable stock planning. both numbers are standard sizes, so holding one of each on the shelf costs little and removes the wait for an outside order.

Yes, provided the old bearing measured the same. The controlling dimensions are 35 mm bore, 62 mm OD, 14 mm width; check the worn part with a caliper before you order, since bore is the one dimension that cannot be shimmed.

It is the seal code. 2NSE is the sealed variant listed here: single row, with a rubber seal on both faces, so the bearing arrives pre-greased and closed on each side.

6007-2NSE is 35 mm bore × 62 mm OD × 14 mm width. 6005-2NSE is 25 mm bore × 47 mm OD × 12 mm width. Both are single-row deep groove ball bearings in carbon steel.

No. The deep groove raceway carries radial load and axial load in both directions, so one bearing per position handles the side load a feed roller puts on the shaft.

Woodworking machines are the listed application. Any seat machined for a 35 × 62 × 14 mm or a 25 × 47 × 12 mm bearing takes the matching number, which covers most spindle and roller positions on that equipment.

Yes, in a woodworking shop. An open bearing lets fine dust reach the ball track; two rubber seals keep the grease in and the dust out, which is the difference between a service interval and a repeat failure.

Read the number off the seal or the ring face. 6005 and 6007 are standard designations, so the number identifies bore, OD and width without measuring anything.

Send the bearing numbers and the quantity you need. Price is quoted per order — the listing carries no fixed figure — so both numbers can go into one request.
