Decoding NTN 6019 ZZ
- 60Series
- Deep groove ball bearings, 60 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
- ZZSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6019 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 6019 ZZ measures 95 mm across the bore and 145 mm across the outside diameter; its width is 24 mm (95 x 145 x 24 mm).

The ZZ suffix on an NTN deep groove ball bearing tells you the bearing arrives with a metal shield on each side. Inside is a single row of balls that handles radial and axial load in either direction, which is why this design turns up so often wherever a straightforward, high-speed bearing with minimal upkeep is required. Motors, pumps, fans, gearboxes and other transmission equipment are typical homes for it.
Reading the code takes two steps. The four digits set the size: the leading pair marks the diameter series, the trailing pair the bore. So 6008ZZ and 6012ZZ sit in one series but differ in shaft size, as do the other references that share those first digits. What the ZZ letters add is the closure itself: two steel shields that hold grease in place and keep coarse dust out, with no contact between shield and balls, so friction stays low and speed is not restricted.
You will find these bearings in general-purpose electric motors, centrifugal pumps, fans and extractors, conveyor lines, machine tools and packaging machinery. Agricultural implements, compressors and power transmission assemblies also use them where the support has to stay compact, mount easily and run with very little attention over the life of the equipment.
Closure choice matters at selection time. ZZ works well where dust is present but no pressurized liquid is; if water or steam is part of the picture, a contact seal is the better call. Alongside that, check the factory lubrication, the internal clearance, and how well the housing and shaft line up, since a support that is out of alignment will shorten bearing life. Fit the bearing with a press or a puller, and never drive it home by hitting the raceway.
When a customer hands over a part number from a different brand, dimensions settle the question: bore, outside diameter and width. Deep groove ball bearings in matching series tend to share those three figures across manufacturers, while the closure suffix can differ from one brand to the next. An unmarked part can be identified by measuring it and comparing the results against the corresponding standard.

Frequently asked questions
- NTN 6019 ZZ bearing: what are its dimensions?
- NTN 6019 ZZ measures 95 mm across the bore and 145 mm across the outside diameter; its width is 24 mm (95 x 145 x 24 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6019.
- What does the ZZ suffix indicate on an NTN bearing?
- It means the bearing is fitted with two metal shields, one per side. They keep dust out and hold the lubricant in, and because they do not touch the balls, neither friction nor speed capacity is affected.
- How should I send a part number to get a quote?
- Message us on WhatsApp or by email with the complete reference, such as 6008ZZ or 6012ZZ, and we will reply promptly. If the designation is unclear, include the shaft and housing dimensions as well.
- Is it possible to swap a bearing from another brand for an NTN one?
- Yes, provided the key dimensions line up: bore diameter, outside diameter and width. Send the original brand's part number and we will give you the matching NTN reference so you can verify interchangeability before mounting.
