NACHI supplier in Romania
Radial and thrust bearings for industrial applications
Founded in 1928 · Headquarters: Tokyo, Japan
Who is NACHI and what does it make?
NACHI makes precision radial and thrust bearings; its headquarters for the European market, NACHI Europe GmbH, is in Krefeld, Germany. The range covers radial ball bearings (deep groove, angular contact, double angular contact, self-aligning), radial roller bearings (cylindrical, tapered, spherical, sheave type), thrust ball and roller bearings, plus accessories such as plummer block housings, adapter sleeves and locking rings. For Romania we can quote both the individual bearing and sets of mounting accessories.
The EXQ-V series of spherical roller bearings is intended by the manufacturer for applications with vibration, with a cage of increased strength and improved corrosion resistance.
For heavily loaded rotating equipment — gearboxes, transmissions, construction machinery — the NACHI range suits as an alternative or complement to the European brands already in use, especially where the radial or axial load exceeds what a standard bearing comfortably covers.
What do we supply from the NACHI range?
| Product | Description |
|---|---|
| Radial Ball Bearings (deep groove and angular contact) | Standard bearings for moderate radial and axial loads, available in deep groove, single or double angular contact, high-speed angular contact and self-aligning variants. They are used on electric motors, pumps, fans and gearboxes where the shaft rotates at medium to high speeds. The customer must tell us the bore, outside diameter and width of the bearing, or the full code if known. |
| Radial Cylindrical and Tapered Roller Bearings | Roller bearings for radial loads higher than those covered by ball bearings, available in cylindrical, tapered and spherical variants. Tapered bearings also take moderate axial loads, and are typical on gearbox shafts and axles. Typical application: industrial gearboxes and construction machinery, where the radial load is high and the speed moderate. |
| EXQ-V Series Spherical Roller Bearings | Spherical roller bearings developed by the manufacturer for applications with vibration, with a cage of increased strength and improved corrosion resistance. The customer must state the estimated radial and axial load and the shaft diameter. |
| Thrust Ball Bearings for Ball Screws | Thrust bearings dedicated to supporting the ends of ball screws in the positioning axes of machine tools. Typical application: CNC machining centres and grinding machines. The customer must specify the ball screw diameter and the expected axial load. |
Why NACHI?
- The EXQ-V series of spherical roller bearings is intended for applications with vibration, with a cage of increased strength and improved corrosion resistance
- A range of radial and thrust bearings, ball and roller, for most types of industrial rotating shafts
- Radial and thrust bearings from the manufacturer's catalogue, for various industrial applications
- Mounting accessories included in the range (housings, sleeves, locking rings), useful for installation without extra parts from another supplier

Where is NACHI equipment used?
- Heavy machinery construction — excavators and cranes
- Automotive — gearboxes, steering, CV joints
- High-speed rail — bearings for bogies and axles
- Mining — equipment with high radial loads and vibration
- Machine tools — supporting ball screw positioning axes
- Industrial air conditioning — bearings for compressors and fans
How do we supply NACHI in Romania?
For NACHI bearings we bring in the product to order through supply channels in the EU, usually in 1–4 weeks after order confirmation — availability of each code is confirmed in the quotation. To give a correct quotation we need the exact bearing code or, if you do not know it, the bore, outside diameter, width and the type of load (radial, axial or combined) of the application. These data come from the manufacturer's documentation; for exact compatibility with an existing shaft, we recommend checking the machine's technical drawing before ordering.
We establish equivalence with another manufacturer's code case by case, and the less common sizes in the range are ordered on request.
Frequently asked questions about NACHI
What is the difference between the EXQ and EXQ-V series in NACHI bearings?
The EXQ series is a distinct series of NACHI spherical roller bearings, with its own brochure, while EXQ-V is developed specially for equipment subject to vibration, with a stronger cage and extra corrosion protection. EXQ-V is justified on vibrating screens, mills or crushing equipment, where the loads are more severe than in normal operation.
What are NACHI angular contact bearings?
NACHI angular contact bearings take radial and axial loads simultaneously, thanks to the contact angle between the balls and the raceways. They are available in high-speed or double-row variants, for increased rigidity, and are frequently used on machine tool or motor shafts where axial positioning accuracy matters as much as durability.
Do you supply NACHI bearings in Romania?
Yes, NACHI bearings can be brought in to order; we do not keep this range on the shelf, and supply usually takes 1–4 weeks, depending on size and availability. We recommend confirming the full bearing code, including the series and the design variant, to avoid confusion between similar types in the manufacturer's catalogue.
What should I send for a quotation on NACHI bearings?
Send the dimensions of the shaft and the housing, the type of load — radial, axial or combined — and the operating conditions, such as speed or the presence of vibration. These data allow the correct choice between ball, tapered roller or spherical bearings, since the NACHI range covers very different mounting and loading situations.
How do I request a NACHI quotation?
Send the NACHI code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
