Description

31.85mm(1.253937"), 31.79mm, 31.81mm,31.83mm precision chrome steel Ball For Bearing, 52100

Introduction

Chrome steel balls, also known as bearing steel balls, are the most widely used bearing balls in the ball and roller bearing industry and various automotive applications. Our company provides chrome steel balls with a size range of 15.875 mm-82.55 mm and an accuracy grade of G 10-G 200. Especially the 22.225mm-82.55mm large-size high-precision chrome steel ball is our main product. XMEC chrome steel balls have perfect precision and outstanding performance. Surface roughness, appropriate hardness, excellent wear resistance. According to customer requirements, steel balls can be produced according to Chinese standards GB/T 308, ISO 3290, ANSI/ABMA, JIS and DIN 5401, etc.

GCr15 steel is a representative steel of high-carbon chromium bearing steel with good overall performance. After quenching and tempering, the hardness is high and uniform, and the wear resistance and contact fatigue resistance are high, good thermal workability. After spheroidizing annealing, it has good workability, but it is sensitive to the formation of white spots.

Steel balls are widely used in bearings, hardware, electronics, mechanical equipment, electric power, mining, metallurgy and other fields.

Our products enjoy high evaluation and satisfaction among customers. Most importantly, we can customize products to meet the various needs of customers.

Packing

Dry or oiled. Standard export packing: 10kg or 20kg per carton,1 ton per pallet or as per customer's requirement. Refer to related pictures.

Firstly we pack the balls in cartons For each cartons,Then, we pack our balls using wooden pallet(Plywood) in our export business:
Put the plastic paper in the pallet(waterproof) at first, then put the ball carton into the pallet, and fix the pallet.
Generally, we offer neutral packing and can according to your requirements.

Time of deliveryThe steel balls are in stock can be shipped around one week. otherwise,it takes about 20-30 days.
20~45 days according to the order quantity.
