Baldur’s industry-unique hubless design was inspired by a visit to the workshop of an early Krownlab collaborator, Rob Roy. There on a table in Rob’s workshop was an enormous 8-inch bearing. Krownlab founder Stefan Andrén put his hand through the inner race and rolled it back and forth over the table.
“You could still put your whole hand through the bearing and I was like, hang on a second, there’s something here,” Andrén said. “I realized you didn’t necessarily have to bolt through the center of the bearing like it’s originally intended to be used, but you could just clamp a portion of the inner race and get this awesome hubless look.”
From that early spark of inspiration was born an iconic sliding door hardware system utterly unique in the industry. Office Insight took notice:
Architectural hardware designer and manufacturer Krownlab announced the launch of Baldur, a versatile, hubless sliding-door hardware system for commercial and large residential interiors, according to Krownlab founder and CEO Stefan Andrén.
“I created Baldur as a high-end, interior iteration of the classic sliding barn door,” Andrén said. “But it’s far more than that. The design possibilities are limitless.”
Baldur can be attached to door panels in three different ways – Top Mount, Face Mount and Glass Mount – and be used in a variety of door configurations. Its patented, industry-unique hubless design employs custom massive unsealed bearings, four inches in diameter and clamped at only one point in the action, which provide Baldur’s movement and distinguish it from all other door systems on the market.
It’s easy to adjust the Baldur system onsite, and among Krownlab’s three mounting systems, Baldur provides the flexibility to work with panels of nearly any size and material, weighing up to 400 lbs. Baldur’s wide steel-on-steel contact surface between its bearing and track ensures even the heaviest doors glide smoothly.
Fabricated from 300- and 400-series stainless steel, in three different finishes – Brushed, Black, and Polished – the Baldur system won’t patina or develop rust, even in damp or humid environments. The product has been tested to 130,000 open-and-close cycles, which is equivalent to 10 years of heavy use, and is suitable for high-traffic commercial environments, requiring virtually no ongoing maintenance. As with all Krownlab systems, it can be cleaned with a lint-free rag, polishing in the same direction as the grain.
