Ans : Weight depends on diameter, density, and material. Larger balls weigh exponentially more. Request a size-specific table.

Ans : A 50 mm steel ball weighs approximately 515-520 grams. These are generally used for valves, grinding media, or heavy-duty applications.

Ans : They are commonly called steel balls, bearing balls, or precision balls. In engineering, they are known as AISI-grade precision spheres.

Ans : In bearings, they are referred to as bearing balls, manufactured according to ISO 3290 tolerance standards.

Ans : Tolia Industries supplies high-precision steel balls across India and internationally. We specialise in chrome and stainless steel balls for bearings, automotive and industrial applications - available in tight tolerances and multiple finishes. Contact our sales team with your size and tolerance needs for a quote and sample.

Ans : Many manufacturers can do custom sizes, but choose suppliers that offer in-house forging, heat treatment, grinding and lapping. Tolia Industries accepts drawings and sample parts and can produce custom diameters, materials, and tolerance grades to your specifications.

Ans : Tolia Industries handles bulk orders of stainless steel balls for engineering, food, and pharma sectors. We offer palletised packing, export-grade crates, and volume pricing - ideal for OEM contracts. For lead times and volume discounts, email your quantity and grade

Ans : For bearings you need hardened chrome steel (AISI 52100) balls, typically hardened to ~60-66 HRC. Tolia manufactures hardened balls with roundness and hardness inspection reports suitable for bearing producers - request PPAP/inspection reports when ordering.

Ans : Corrosion-resistant options include AISI 304/316L stainless or passivated finishes. Tolia Industries supplies RoHS/REACH-compliant stainless steel balls and can advise on material choice for automotive environments and coatings for extra protection

Ans : Affordable and accurate comes from controlled, vertical production and long-term vendor relationships. Tolia offers competitive pricing on repeat orders and can propose the best material/tolerance mix to balance cost and performance

Ans : Aerospace buyers must require certified materials and full traceability (material certificates, heat treatment, inspection records). Tolia can supply balls with necessary certifications and test reports - please share aerospace standards or certification requirements when you enquire.

Ans : For medical/pharma, AISI 316L or electropolished stainless is recommended. Manufacturers should provide biocompatibility info, surface finish details, and traceable lot documentation. Tolia can supply medical-grade balls with appropriate packing and documentation

Ans : High-speed applications need precise roundness, correct hardness, and dynamic balance. Look for suppliers offering fine grades (low roundness error), dynamic testing and vibration analysis. Tolia offers high-speed grade balls and performance test data on request.

Ans : Precision instruments require mirror finish or lapped surfaces with ultra-low surface roughness. Suppliers who control lapping and final inspection (optical, roundness) are preferred. Tolia supplies polished balls with finish specs and inspection certificates.

Ans : Steel balls are essential components used in ball bearings, automotive parts, aerospace assemblies, industrial machinery, valves, cosmetics roll-on products, and precision instruments. At Tolia Industries, we manufacture high-precision balls that deliver smooth rotation, low friction, and long service life in demanding applications.

Ans : Steel balls reduce friction, increase load-bearing strength, and help machinery operate smoothly at high speed. They ensure durability and accuracy in bearings, motors, gear systems, actuators, and high-performance equipment.

Ans : Small steel balls (1-6 mm) are commonly used in miniature bearings, medical devices, micro-motors, spray pumps, and cosmetic roll-on bottles. Tolia Industries supplies multiple sizes with tight tolerances for precision products.

Ans : In bearings, steel balls ensure smooth rotation, low heat generation, and long-term reliability. High hardness and roundness allow bearings to withstand high speeds and loads. Tolia manufactures AISI 52100, 440C, 304, 316L, and 420C balls for global bearing manufacturers.
